Marijuana information

Marijuana is a green or gray mixture of dried, shredded flowers and leaves of the hemp plant (Cannabis sativa). It is the most often used illegal drug in this country. All forms of cannabis are mind-altering (psychoactive) drugs; they all contain THC (delta-9-tetrahydrocannabinol), the main active chemical in marijuana. There are about 400 chemicals in a cannabis plant, but THC is the one that affects the brain the most.

There are many different names for marijuana. Slang terms for drugs change quickly, and they vary from one part of the country to another. They may even differ across sections of a large city. Terms from years ago, such as pot, herb, grass, weed, Mary Jane, and reefer, are still used. You might also hear the names skunk, boom, gangster, kif, or ganja. There are also street names for different strains or "brands" of marijuana, such as "Texas tea," "Maui wowie," and "Chronic." A recent book of American slang lists more than 200 terms for various kinds of marijuana.

Marijuana's effect on the user depends on the strength or potency of the THC it contains. THC potency has increased since the 1970s but has been about the same since the mid-1980s. The strength of the drug is measured by the average amount of THC in test samples confiscated by law enforcement agencies.

Most ordinary marijuana has an average of 3 percent THC.

Sinsemilla (made from just the buds and flowering tops of female plants) has an average of 7.5 percent THC, with a range as high as 24 percent.

Hashish (the sticky resin from the female plant flowers) has an average of 3.6 percent, with a range as high as 28 percent.

Hash oil, a tar-like liquid distilled from hashish, has an average of 16 percent, with a range as high as 43 percent.

Marijuana use

Most users roll loose marijuana into a cigarette (called a "joint"). The drug can also be smoked in a water pipe, called a "bong." Some users mix marijuana into foods or use it to brew a tea. Marijuana cigarettes or blunts often include crack cocaine, a combination known by various street names, such as "primos" or "woolies." Joints and blunts often are dipped in PCP and are called "happy sticks," "wicky sticks," "love boat," or "tical." Hash users either smoke the drug in a pipe or mix it with tobacco and smoke it as a cigarette. Lately, young people have a new method for smoking marijuana: they slice open cigars and replace the tobacco with marijuana, making what's called a "blunt." When the blunt is smoked with a 40 oz. bottle of malt liquor, it is called a "B-40."

Marijuana addiction

Not everyone who uses marijuana becomes addicted, when a user begins to seek out and take the drug compulsively, that person is said to be dependent on the drug or addicted to it. In 1995, 165,000 people entering drug rehab programs reported marijuana as their primary drug of abuse, showing they needed help to stop using.

Some heavy users of marijuana show signs of dependence because when they do not use the drug, they develop withdrawal symptoms. Some subjects in an experiment on marijuana withdrawal had symptoms, such as restlessness, loss of appetite, trouble with sleeping, weight loss, and shaky hands.

According to one study, marijuana use by teenagers who have prior serious antisocial problems can quickly lead to dependence on the drug. That study also found that, for troubled teenagers using tobacco, alcohol, and marijuana, progression from their first use of marijuana to regular use was about as rapid as their progression to regular tobacco use, and more rapid than the progression to regular use of alcohol.
