Facts about Heroin

Heroin is a rapidly acting drug derived from the Asian opium poppy plant. Heroin is processed from morphine, a naturally occurring substance extracted from the seedpod of the Asian poppy. Heroin usually appears as a white or brown powder. Street names for heroin include “smack,” “H,” “skag,” and “junk.” Other names may refer to types of heroin produced in a specific geographical area, such as “Mexican black tar.”
Health Hazards

Heroin abuse is associated with serious health conditions, including fatal overdose, spontaneous abortion, collapsed veins, and, particularly in users who inject the drug, infectious diseases, including HIV/AIDS and hepatitis.

The short-term effects of heroin abuse appear soon after a single dose and disappear in a few hours. After an injection of heroin, the user reports feeling a surge of euphoria (”rush”) accompanied by a warm flushing of the skin, a dry mouth, and heavy extremities. Following this initial euphoria, the user goes “on the nod,” an alternately wakeful and drowsy state. Mental functioning becomes clouded due to the depression of the central nervous system. Long-term effects of heroin appear after repeated use for some period of time. Chronic users may develop collapsed veins, infection of the heart lining and valves, abscesses, cellulitis, and liver disease. Pulmonary complications, including various types of pneumonia, may result from the poor health condition of the abuser, as well as from heroin’s depressing effects on respiration.

Heroin abuse during pregnancy and its many associated environmental factors (e.g., lack of prenatal care) have been associated with adverse consequences including low birth weight, an important risk factor for later developmental delay.

In addition to the effects of the drug itself, street heroin may have additives that do not readily dissolve and result in clogging the blood vessels that lead to the lungs, liver, kidneys, or brain. This can cause infection or even death of small patches of cells in vital organs.
Tolerance, Addiction, and Withdrawal

With regular heroin use, tolerance develops. This means the abuser must use more heroin to achieve the same intensity of effect. As higher doses are used over time, physical dependence and addiction develop. With physical dependence, the body has adapted to the presence of the drug and withdrawal symptoms may occur if use is reduced or stopped.

Withdrawal, which in regular abusers may occur as early as a few hours after the last administration, produces drug craving, restlessness, muscle and bone pain, insomnia, diarrhea and vomiting, cold flashes with goose bumps (”cold turkey”), kicking movements (”kicking the habit”), and other symptoms. Major withdrawal symptoms peak between 48 and 72 hours after the last dose and subside after about a week. Sudden withdrawal by heavily dependent users who are in poor health is occasionally fatal, although heroin withdrawal is considered less dangerous than alcohol or barbiturate withdrawal.
Treatment

There is a broad range of treatment options for heroin addiction, including medications as well as behavioral therapies. Science has taught us that when medication treatment is integrated with other supportive services, patients are often able to stop heroin (or other opiate) use and return to more stable and productive lives.

In November 1997, the National Institutes of Health (NIH) convened a Consensus Panel on Effective Medical Treatment of Heroin Addiction. The panel of national experts concluded that opiate drug addictions are diseases of the brain and medical disorders that indeed can be treated effectively. The panel strongly recommended broader access to methadone maintenance treatment programs for people who are addicted to heroin or other opiate drugs; and the Federal and State regulations and other barriers impeding this access be eliminated. This panel also stressed the importance of providing substance abuse counseling, psychosocial therapies, and other supportive services to enhance retention and successful outcomes in methadone maintenance treatment programs. The panel’s full consensus statement is available by visiting the NIH Consensus Development Program Web site at consensus.nih.gov.

Methadone, a synthetic opiate medication that blocks the effects of heroin for about 24 hours, has a proven record of success when prescribed at a high enough dosage level for people addicted to heroin. Other approved medications are naloxone, which is used to treat cases of overdose, and naltrexone, both of which block the effects of morphine, heroin, and other opiates.

Buprenorphine is the most recent addition to the array of medications available for treating addiction to heroin and other opiates. This medication is different from methadone in that it offers less risk of addiction and can be dispensed in the privacy of a doctor’s office. Several other medications for use in heroin treatment programs are also under study.

For the pregnant heroin abuser, methadone maintenance combined with prenatal care and a comprehensive drug treatment program can improve many of the detrimental maternal and neonatal outcomes associated with untreated heroin abuse. There is preliminary evidence that buprenorphine also is safe and effective in treating heroin dependence during pregnancy, although infants exposed to methadone or buprenorphine during pregnancy typically require treatment for withdrawal symptoms. For women who do not want or are not able to receive pharmacotherapy for their heroin addiction, detoxification from opiates during pregnancy can be accomplished with relative safety, although the likelihood of relapse to heroin use should be considered.

There are many effective behavioral treatments available for heroin addiction. These can include residential and outpatient approaches. Several new behavioral therapies are showing particular promise for heroin addiction. Contingency management therapy uses a voucher-based system, where patients earn “points” based on negative drug tests, which they can exchange for items that encourage healthful living. Cognitive-behavioral interventions are designed to help modify the patient’s thinking, expectancies, and behaviors and to increase skills in coping with various life stressors.
Extent of Use

Monitoring the Future (MTF) Survey *
According to the 2006 MTF, rates of lifetime** and past year heroin use were stable among all three grades surveyed. However, 8th-graders reported significant declines in past month use of heroin, from 0.5 percent in 2005 to 0.3 percent in 2006.

Recent peaks in past year heroin use were observed in 1996 for 8th-graders (1.6 percent), 1997-2000 for 10th-graders (1.4 percent), and 2000 for 12th-graders (1.5 percent). Past year use in 2006 was significantly lower than these peak years of use for all three grades.

More facts about marihuana

Well, since this drug is used by the most people on our planet i’ve decided to put in some more information on this.

What is Marijuana?

Call it pot, grass, weed, or any one of nearly 200 other names, marijuana is, by far, the world’s most commonly used illicit drug—and far more dangerous than most users realize. So, there is just cause for alarm when adolescent marijuana use increases, as it did in the mid-1990’s, and the age at which youngsters first experiment with pot starts to drops.

Marijuana has been around for a long while. Its source, the hemp plant (cannabis sativa), was being cultivated for psychoactive properties more than 2,000 years ago. Although cannabis contains at least 400 different chemicals, its main mind-altering ingredient is THC (delta-9-tetrahydrocannabinol).The amount of THC in marijuana determines the drug’s strength, and THC levels are affected by a great many factors, including plant type, weather, soil, and time of harvest. Sophisticated cannabis cultivation of today produces high levels of THC and marijuana that is far more potent than pot of the past. THC content of marijuana, which averaged less than 1 percent in 1974, rose to an average 4 percent by 1994.

For the highly popular form of marijuana called Sinsemilla (from the Spanish “without seeds”), made from just the buds and flowering tops of female plants, THC content averages 7.5 percent and ranges as high as 24 percent. As for hashish, a resin made from flowers of the female plant, THC levels may be five to ten times higher than crude marijuana’s.

How is it Used?

Marijuana and other cannabis products are usually smoked, sometimes in a pipe or water pipe, but most often in loosely rolled cigarettes known as “joints.” Some users will slice open and hollow out cigars, replacing the tobacco with marijuana, to make what are called “blunts.” Joints and blunts may be laced with other substances, including crack cocaine and the potent hallucinogen phencyclidine (PCP), substantially altering effects of the drug.

Smoking, however, is not the sole route of administration. Marijuana can be brewed into tea or mixed in baked products (cookies or brownies).

How Does it Affect You?

A mild hallucinogen, marijuana has some of alcohol’s depressant and disinhibiting properties. User reaction, however, is heavily influenced by expectations and past experience, and many first-time users feel nothing at all.

Effects of smoking are generally felt within a few minutes and peak in 10 to 30 minutes. They include dry mouth and throat, increased heart rate, impaired coordination and balance, delayed reaction time, and diminished short-term memory. Moderate doses tend to induce a sense of well-being and a dreamy state of relaxation that encourages fantasies, renders some users highly suggestible, and distorts perception (making it dangerous to operate machinery, drive a car or boat, or ride a bicycle). Stronger doses prompt more intense and often disturbing reactions including paranoia and hallucinations.

Most of marijuana’s short-term effects wear off within two or three hours. The drug itself, however, tends to linger on. THC is a fat-soluble substance and will accumulate in fatty tissues in the liver, lungs, testes, and other organs. Two days after smoking marijuana, one-quarter of the THC content may still be retained. It will show up in urine tests three days after use, and traces may be picked up by sensitive blood tests two to four weeks later.

The Impact on the Mind

Marijuana use reduces learning ability. Research has been piling up of late demonstrating clearly that marijuana limits the capacity to absorb and retain information. A 1995 study of college students discovered that the inability of heavy marijuana users to focus, sustain attention, and organize data persists for as long as 24 hours after their last use of the drug. Earlier research, comparing cognitive abilities of adult marijuana users with non-using adults, found that users fall short on memory as well as math and verbal skills. Although it has yet to be proven conclusively that heavy marijuana use can cause irreversible loss of intellectual capacity, animal studies have shown marijuana-induced structural damage to portions of the brain essential to memory and learning.

The Impact on the Body

Chronic marijuana smokers are prey to chest colds, bronchitis, emphysema, and bronchial asthma. Persistent use will damage lungs and airways and raise the risk of cancer. There is just as much exposure to cancer-causing chemicals from smoking one marijuana joint as smoking five tobacco cigarettes. And there is evidence that marijuana may limit the ability of the immune system to fight infection and disease.

Marijuana also affects hormones. Regular use can delay the onset of puberty in young men and reduce sperm production. For women, regular use may disrupt normal monthly menstrual cycles and inhibit ovulation. When pregnant women use marijuana, they run the risk of having smaller babies with lower birth weights, who are more likely than other babies to develop health problems. Some studies have also found indications of developmental delays in children exposed to marijuana before birth.

Marijuana as Medicine

Although U.S. law classifies marijuana as a Schedule I controlled substance (which means it has no acceptable medical use), a number of patients claim that smoking pot has helped them deal with pain or relieved the symptoms of glaucoma, the loss of appetite that accompanies AIDS, or nausea caused by cancer chemotherapy. There is, however, no solid evidence that smoking marijuana creates any greater benefits than approved medications (including oral THC) now used to treat these patients, relieve their suffering, or mitigate the side effects of their treatment. Anecdotal assertions of beneficial effects have yet to be confirmed by controlled scientific research.

Teens and Marijuana
Although dangers exist for marijuana users of all ages, risk is greatest for the young. For them, the impact of marijuana on learning is critical, and pot often proves pivotal in the failure to master vital interpersonal coping skills or make appropriate life-style choices. Thus, marijuana can inhibit maturity.

Another concern is marijuana’s role as a “gateway drug,” which makes subsequent use of more potent and disabling substances more likely. The Center on Addiction and Substance Abuse at Columbia University found adolescents who smoke pot 85 times more likely to use cocaine than their non–pot smoking peers. And 60 percent of youngsters who use marijuana before they turn 15 later go on to use cocaine.

But many teens encounter serious trouble well short of the “gateway.” Marijuana is, by itself, a high-risk substance for adolescents. More than adults, they are likely to be victims of automobile accidents caused by marijuana’s impact on judgment and perception. Casual sex, prompted by compromised judgment or marijuana’s disinhibiting effects, leaves them vulnerable not only to unwanted pregnancy but also to sexually transmitted diseases (STDs).

Marijuana Dangers

• Impaired perception
• Diminished short-term memory
• Loss of concentration and coordination
• Impaired judgement
• Increased risk of accidents
• Loss of motivation
• Diminished inhibitions
• Increased heart rate
• Anxiety, panic attacks, and paranoia
• Hallucinations
• Damage to the respiratory, reproductive, and immune systems
• Increased risk of cancer
• Psychological dependency

Cancer Facts

I was just lying in bed when i thought of some information which the public eye really needs, it’s facts about cancer. Cancer is a very terrible disease and i would not wish something like that even on my enemy. Thank god that cancer can be cured thanks to our scientists who are figuring out ways to cure it every day.

What is cancer?

Cancer is a group of many related diseases that begin in cells, the body’s basic building blocks. To understand cancer, it is helpful to know what happens when normal cells become cancerous.

The body is made up of many types of cells. Normally, cells grow and divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, and old cells do not die when they should. The extra cells form a mass of tissue called a growth or tumor. Not all tumors are cancerous; tumors can be benign or malignant.

Benign tumors are not cancer. They can often be removed and, in most cases, they do not come back. Cells in benign tumors do not spread to other parts of the body. Most important, benign tumors are rarely a threat to life.

Malignant tumors are cancer. Cells in malignant tumors are abnormal and divide without control or order. Cancer cells invade and destroy the tissue around them. Cancer cells can also break away from a malignant tumor and enter the bloodstream or lymphatic system.

Blood vessels include a network of arteries, capillaries, and veins through which the blood circulates in the body. The lymphatic system carries lymph and white blood cells through lymphatic vessels (thin tubes) to all the tissues of the body. By moving through the bloodstream or lymphatic system, cancer can spread from the primary (original) cancer site to form new tumors in other organs. The spread of cancer is called metastasis.
What causes cancer?

Scientists have learned that cancer is caused by changes in genes that normally control the growth and death of cells. Certain lifestyle and environmental factors can change some normal genes into genes that allow the growth of cancer. Many gene changes that lead to cancer are the result of tobacco use, diet, exposure to ultraviolet (UV) radiation from the sun, or exposure to carcinogens (cancer-causing substances) in the workplace or in the environment. Some gene alterations are inherited (from one or both parents). However, having an inherited gene alteration does not always mean that the person will develop cancer; it only means that the chance of getting cancer is increased. Scientists continue to examine the factors that may increase or decrease a person’s chance of developing cancer.

Although being infected with certain viruses, such as the human papillomavirus (HPV), hepatitis B and C (HepB and HepC), and human immunodeficiency virus (HIV), increases the risk of some types of cancer, cancer itself is not contagious. A person cannot catch cancer from someone who has this disease. Scientists also know that an injury or bruise does not cause cancer.
Can cancer be prevented?

Although there is no guaranteed way to prevent cancer, people can reduce their risk (chance) of developing cancer by:

* not using tobacco products
* choosing foods with less fat and eating more vegetables, fruits, and whole grains
* exercising regularly and maintaining a lean weight
* avoiding the harmful rays of the sun, using sunscreen, and wearing clothing that protects the skin
* talking with a doctor about the possible benefits of drugs proven to reduce the risk of certain cancers

Although many risk factors can be avoided, some, such as inherited conditions, are unavoidable. Still, it is helpful to be aware of them. It is also important to keep in mind that not everyone with a particular risk factor for cancer actually gets the disease; in fact, most do not. People who have an increased likelihood of developing cancer can help protect themselves by avoiding risk factors (see Question 2) whenever possible and by getting regular checkups so that, if cancer develops, it is likely to be found and treated early. Treatment is often more effective when cancer is detected early. Screening exams, such as sigmoidoscopy or the fecal occult blood test, mammography, and the Pap test, can detect precancerous conditions (which can be treated before they turn into cancer) and early-stage cancer.

The NCI is conducting many cancer prevention studies to explore ways to reduce the risk of developing cancer. These studies are evaluating dietary supplements, chemopreventive agents, nutrition, personal behaviors, and other factors that may prevent cancer. More information about cancer prevention trials is available in the following NCI resources:

What are some of the common signs and symptoms of cancer?

Cancer can cause a variety of symptoms. Possible signs of cancer include the following:

* new thickening or lump in the breast or any other part of the body
* new mole or an obvious change in the appearance of an existing wart or mole
* a sore that does not heal
* nagging cough or hoarseness
* changes in bowel or bladder habits
* persistent indigestion or difficulty swallowing
* unexplained changes in weight
* unusual bleeding or discharge

When these or other symptoms occur, they are not always caused by cancer. They can be caused by infections, benign tumors, or other problems. It is important to see a doctor about any of these symptoms or about other physical changes. Only a doctor can make a diagnosis. A person with these or other symptoms should not wait to feel pain because early cancer usually does not cause pain.

If symptoms occur, the doctor may perform a physical examination, order blood work and other tests, and/or recommend a biopsy. In most cases, a biopsy is the only way to know for certain whether cancer is present. During a biopsy, the doctor removes a sample of tissue from the abnormal area. A pathologist studies the tissue under a microscope to identify cancer cells.
How is cancer treated?

Cancer treatment can include surgery, radiation therapy, chemotherapy, hormone therapy, and biological therapy. The doctor may use one method or a combination of methods, depending on the type and location of the cancer, whether the disease has spread, the patient’s age and general health, and other factors. Because treatment for cancer can also damage healthy cells and tissues, it often causes side effects. Some patients may worry that the side effects of treatment are worse than the disease. However, patients and doctors generally discuss the treatment options, weighing the likely benefits of killing cancer cells and the risks of possible side effects. Doctors can suggest ways to reduce or eliminate problems that may occur during and after treatment.

Surgery is an operation to remove cancer. The side effects of surgery depend on many factors, including the size and location of the tumor, the type of operation, and the patient’s general health. Patients have some pain after surgery, but this pain can be controlled with medicine. It is also common for patients to feel tired or weak for a while after surgery.

Patients may worry that having a biopsy or other type of surgery for cancer will spread the disease. This is a very rare occurrence because surgeons take special precautions to prevent cancer from spreading during surgery. Also, exposing cancer to air during surgery does not cause the disease to spread.

Radiation therapy (also called radiotherapy) uses high-energy rays to kill cancer cells in a targeted area. Radiation can be given externally by a machine that aims radiation at the tumor area. It can also be given internally; needles, seeds, wires, or catheters containing a radioactive substance are placed directly in or near the tumor. Radiation treatments are painless. The side effects are usually temporary, and most can be treated or controlled. Patients are likely to feel very tired, especially in the later weeks of treatment. Radiation therapy may also cause a decrease in the number of white blood cells, which help protect the body against infection. With external radiation, it is also common to have temporary hair loss in the treated area and for the skin to become red, dry, tender, and itchy.

There is no risk of radiation exposure from coming in contact with a patient undergoing external radiation therapy. External radiation does not cause the body to become radioactive. With internal radiation (also called implant radiation), a patient may need to stay in the hospital, away from other people, while the radiation level is highest. Implants may be permanent or temporary. The amount of radiation in a permanent implant goes down to a safe level before the person leaves the hospital. With a temporary implant, there is no radioactivity left in the body after the implant is removed.

Chemotherapy is the use of drugs that kill cancer cells throughout the body. Healthy cells can also be harmed, especially those that divide quickly. The doctor may use one drug or a combination of drugs. The side effects of chemotherapy depend mainly on the drug(s) and the dose(s) the patient receives. Hair loss is a common side effect of chemotherapy; however, not all anticancer drugs cause loss of hair. Anticancer drugs may also cause temporary fatigue, poor appetite, nausea and vomiting, diarrhea, and mouth and lip sores. Drugs that prevent or reduce nausea and vomiting can help with some of these side effects. Normal cells usually recover when chemotherapy is over, so most side effects gradually go away after treatment ends.

Hormone therapy is used to treat certain cancers that depend on hormones for their growth. It works by keeping cancer cells from getting or using the hormones they need to grow. This treatment may include the use of drugs that stop the production of certain hormones or that change the way hormones work. Another type of hormone therapy is surgery to remove organs that make hormones. For example, the ovaries may be removed to treat breast cancer, or the testicles may be removed to treat prostate cancer.

Hormone therapy can cause a number of side effects. Patients may feel tired, or have fluid retention, weight gain, hot flashes, nausea and vomiting, changes in appetite, and, in some cases, blood clots. Hormone therapy may also cause bone loss in premenopausal women. Depending on the type of hormone therapy used, these side effects may be temporary, long lasting, or permanent.

Biological therapy uses the body’s immune system, directly or indirectly, to fight disease and to lessen some of the side effects of cancer treatment. Monoclonal antibodies, interferon, interleukin-2, and colony-stimulating factors are some types of biological therapy.

The side effects caused by biological therapy vary with the specific treatment. In general, these treatments tend to cause flu-like symptoms, such as chills, fever, muscle aches, weakness, loss of appetite, nausea, vomiting, and diarrhea. Patients also may bleed or bruise easily, get a skin rash, or have swelling. These problems can be severe, but they go away after the treatment stops.
Are clinical trials (research studies) available? Where can people get more information about clinical trials?

Yes. Clinical trials are an important treatment option for many cancer patients. To develop new, more effective treatments, and better ways to use current treatments, the NCI is sponsoring clinical trials in many hospitals and cancer centers around the country. Clinical trials are a critical step in the development of new methods of treatment. Before any new treatment can be recommended for general use, doctors conduct clinical trials to find out whether the treatment is safe for patients and effective against the disease.

People interested in taking part in a clinical trial should talk with their doctor. Information about clinical trials is available from the NCI’s Cancer Information Service (CIS) (see below) at 1–800–4–CANCER and in the NCI booklet Taking Part in Clinical Trials: What Cancer Patients Need To Know, which is available at http://www.cancer.gov/publications on the Internet. This booklet describes how research studies are carried out and explains their possible benefits and risks. Further information about clinical trials is available at http://www.cancer.gov/clinicaltrials on the NCI’s Web site. The Web site offers detailed information about specific ongoing treatment trials as well as trials focused on prevention, screening, and diagnosis by linking to PDQ®, the NCI’s comprehensive cancer information database. The CIS also provides information from PDQ.
Does cancer always cause pain?

Having cancer does not always mean having pain. Whether a patient has pain may depend on the type of cancer, the extent of the disease, and the patient’s tolerance for pain. Most pain occurs when the cancer grows and presses against bones, organs, or nerves. Pain may also be a side effect of treatment. However, pain can generally be relieved or reduced with prescription medicines or over-the-counter drugs recommended by the doctor. Other ways to reduce pain, such as relaxation exercises, may also be useful. Pain should not be accepted as an unavoidable part of having cancer. It is important for patients to talk about pain so steps can be taken to help relieve it. The fear of addiction or “losing control” should not stop patients from taking pain medication. Patients who take medications for cancer pain, as prescribed by their doctor, rarely become addicted to them. In addition, changing the dose or type of medication can usually help if the patient has troublesome side effects.

Abortion Facts

• When does the unborn baby’s heart begin to beat?

The heartbeat begins on the 21st day after conception.

• When does the brain begin to function?

  Electrical brain waves have been recorded as early as forty days.

• How early can a baby survive outside the mother’s womb?

  Currently, twenty weeks is considered the accepted minimum. However, this time will be reduced as medical technology continues to improve.

• What about cases of rape and incest?

Pregnancy from rape is extremely rare. As reasons for legalizing abortion rape and incest are nothing more than emotional screens used by those profiting from abortion. But we must approach the victim of rape or incest with great compassion. The woman has been subjected to an ugly trauma, and she needs love, support and help. But she has been the victim of one violent act. Should we now ask her to be a party to a second violent act -that of abortion? Unquestionably, many would return the violence of killing an innocent baby for the violence of rape. But, before making this decision, remember that most of the trauma has already occurred. She has been raped. That trauma will live with her all her life. Furthermore, this girl did not report for help, but kept this to herself. For several weeks or months, she has thought of little else. Now, she has finally asked for help, has shared her upset, and should be in a supportive situation.

• But what about the child with disease who will die a slow death or live his life as a burden to his family?

  Do you believe the new “ethic” should be that we kill the suffering or burdensome? Some of these cases are tragic, some are also inspirational. We cannot assume the responsibility for killing an unborn child simply because the child has not yet been seen in public. The child’s place of residence does not change what abortion does - kill a human being.

• What about the population boom? We can hardly feed the people of the world now!

  True, the population of the world is growing, but population is not much of a problem in the United States. With a birth every 8 seconds and a death every 11 seconds, the U.S. population is growing at less than one percent per year.

  Population growth or decline compares replacement of the current number of reproductive age individuals with the number of babies being born. By this measure, the United States is now in a sharp population decline.

• How can a girl give up her own baby for adoption and go through life never knowing what is happening to her child?

Which is better to remember, “I gave my baby life. And because I loved him, I gave him into the arms of a loving couple” - or to remember, “I selfishly ended my baby’s life?”
