Myths and Facts About Marijuana

Myth: Marijuana Can Cause Permanent Mental Illness. Among adolescents, even occasional marijuana use may cause psychological damage. During intoxication, marijuana users become irrational and often behave erratically.

Fact: There is no convincing scientific evidence that marijuana causes psychological damage or mental illness in either teenagers or adults. Some marijuana users experience psychological distress following marijuana ingestion, which may include feelings of panic, anxiety, and paranoia. Such experiences can be frightening, but the effects are temporary. With very large doses, marijuana can cause temporary toxic psychosis. This occurs rarely, and almost always when marijuana is eaten rather than smoked. Marijuana does not cause profound changes in people's behavior.

Myth: Marijuana is Highly Addictive. Long term marijuana users experience physical dependence and withdrawal, and often need professional drug treatment to break their marijuana habits.

Fact: Most people who smoke marijuana smoke it only occasionally. A small minority of Americans - less than 1 percent - smoke marijuana on a daily basis. An even smaller minority develop a dependence on marijuana. Some people who smoke marijuana heavily and frequently stop without difficulty. Others seek help from drug treatment professionals. Marijuana does not cause physical dependence. If people experience withdrawal symptoms at all, they are remarkably mild.

Myth: Marijuana Is More Potent Today Than In The Past. Adults who used marijuana in the 1960s and 1970s fail to realize that when today's youth use marijuana they are using a much more dangerous drug.

Fact: When today's youth use marijuana, they are using the same drug used by youth in the 1960s and 1970s. A small number of low-THC samples seized by the Drug Enforcement Administration are used to calculate a dramatic increase in potency. However, these samples were not representative of the marijuana generally available to users during this era. Potency data from the early 1980s to the present are more reliable, and they show no increase in the average THC content of marijuana. Even if marijuana potency were to increase, it would not necessarily make the drug more dangerous. Marijuana that varies quite substantially in potency produces similar psychoactive effects.

Myth: Marijuana Offenses Are Not Severely Punished. Few marijuana law violators are arrested and hardly anyone goes to prison. This lenient treatment is responsible for marijuana continued availability and use.

Fact: Marijuana arrests in the United States doubled between 1991 and 1995. In 1995, more than one-half-million people were arrested for marijuana offenses. Eighty-six percent of them were arrested for marijuana possession. Tens of thousands of people are now in prison or marijuana offenses. An even greater number are punished with probation, fines, and civil sanctions, including having their property seized, their driver's license revoked, and their employment terminated. Despite these civil and criminal sanctions, marijuana continues to be readily available and widely used.

Myth: Marijuana is More Damaging to the Lungs Than Tobacco. Marijuana smokers are at a high risk of developing lung cancer, bronchitis, and emphysema.

Fact: Moderate smoking of marijuana appears to pose minimal danger to the lungs. Like tobacco smoke, marijuana smoke contains a number of irritants and carcinogens. But marijuana users typically smoke much less often than tobacco smokers, and over time, inhale much less smoke. As a result, the risk of serious lung damage should be lower in marijuana smokers. There have been no reports of lung cancer related solely to marijuana, and in a large study presented to the American Thoracic Society in 2006, even heavy users of smoked marijuana were found not to have any increased risk of lung cancer. Unlike heavy tobacco smokers, heavy marijuana smokers exhibit no obstruction of the lung's small airway. That indicates that people will not develop emphysema from smoking marijuana.

Myth: Marijuana Has No Medicinal Value. Safer, more effective drugs are available. They include a synthetic version of THC, marijuana's primary active ingredient, which is marketed in the United States under the name Marinol.

Fact: Marijuana has been shown to be effective in reducing the nausea induced by cancer chemotherapy, stimulating appetite in AIDS patients, and reducing intraocular pressure in people with glaucoma. There is also appreciable evidence that marijuana reduces muscle spasticity in patients with neurological disorders. A synthetic capsule is available by prescription, but it is not as effective as smoked marijuana for many patients. Pure THC may also produce more unpleasant psychoactive side effects than smoked marijuana. Many people use marijuana as a medicine today, despite its illegality. In doing so, they risk arrest and imprisonment.

Myth: Marijuana is a Gateway Drug. Even if marijuana itself causes minimal harm, it is a dangerous substance because it leads to the use of "harder drugs" like heroin, LSD, and cocaine.

Fact: Marijuana does not cause people to use hard drugs. What the gateway theory presents as a causal explanation is a statistic association between common and uncommon drugs, an association that changes over time as different drugs increase and decrease in prevalence. Marijuana is the most popular illegal drug in the United States today. Therefore, people who have used less popular drugs such as heroin, cocaine, and LSD, are likely to have also used marijuana. Most marijuana users never use any other illegal drug. Indeed, for the large majority of people, marijuana is a terminus rather than a gateway drug.

Myth: Marijuana's Harms Have Been Proved Scientifically. In the 1960s and 1970s, many people believed that marijuana was harmless. Today we know that marijuana is much more dangerous than previously believed.

Fact: In 1972, after reviewing the scientific evidence, the National Commission on Marihuana and Drug Abuse concluded that while marijuana was not entirely safe, its dangers had been grossly overstated. Since then, researchers have conducted thousands of studies of humans, animals, and cell cultures. None reveal any findings dramatically different from those described by the National Commission in 1972. In 1995, based on thirty years of scientific research editors of the British medical journal Lancet concluded that "the smoking of cannabis, even long term, is not harmful to health."

Study says alcohol more harmful than marijuana

A major new study into drugs, published in the British medical journal The Lancet, has concluded that alcohol and tobacco are more dangerous than many highly illegal drugs. They are listed in the top 10 most dangerous substances in the study. Researchers believe British law should classify alcohol and tobacco the same as hard drugs such as heroin and cocaine. Head researcher Professor David Nutt of Britain's Bristol University suggested a new classification of harmful substances. He said it needed to be based on the actual risks posed to society. Professor Nutt said the new system was necessary in Britain as the existing one was out of date: "The current drug system is ill thought-out and arbitrary,” he said. He added there was no scientific basis for excluding alcohol and tobacco as serious drugs.

Professor Nutt and his colleagues used three factors to find out how harmful a drug is: the physical harm to the user, how addictive the drug is, and the impact it has on society. The researchers were experts in drug addiction, lawyers and police officers with scientific or medical backgrounds and doctors. All of them agreed on the dangers of alcohol and tobacco. They ranked alcohol as the fifth and tobacco as the ninth most harmful drugs. Heroin and cocaine finished top, while marijuana was eleventh and Ecstasy finished last in the list of 20 drugs. The latter two are illegal in Britain and America, while alcohol and tobacco are legal. Tobacco causes 40 percent of all hospital illnesses, while alcohol is blamed for more than half of all visits to hospital emergency rooms. They also harm society in other ways. They damage families and stretch police services.

Alcohol is a sedative hypnotic. It is a powerful drug available to virtually anyone who wants to try it. Buzzed: The straight facts about the most used and abused drugs from alcohol to ecstasy describes the effects of alcohol on the body: Buzzed Book Jacket Graphic

* About 20 percent of alcohol is absorbed through stomach, and most of the rest is absorbed through the small intestine. Alcohol molecules are carried through the bloodstream and come into contact with the cells of virtually all the organs. When someone drinks on an empty stomach, the blood absorbs the alcohol rapidly. The body also absorbs higher concentrations of alcohol, such as mixed drinks or shots, very quickly


Physical State

* After drinking, people usually feel pleasure and become talkative at first. The feelings are usually replaced by drowsiness as the alcohol is eliminated from body, and the drinker may become withdrawn. This pattern often encourages people to drink more to keep the buzz going.
* Immediate medical attention is necessary if a person becomes unconscious, is impossible to arouse or seems to have trouble breathing.
* Drinking a high concentration of alcohol in a short period of time can suppress the centers of the brain that control breathing and cause a person to pass out or even die.
* When people pass out, their bodies continue to absorb alcohol. The amount of alcohol in the blood can reach dangerous levels, and they can die in their sleep. Continue to check on someone who has gone to sleep drunk. Do not leave that person alone.
* It is dangerous to combine alcohol with other drugs, especially those that make you sleepy
* Most alcohol is metabolized in the liver and then excreted. When someone drinks more alcohol than their liver can handle efficiently, the additional alcohol accumulates in the blood and body tissues.
