Marijuana is still the illegal drug most often abused in the United States. Its continued high prevalence rate, particularly among teens, indicates that we still have a long way to go. In addition, because many parents of present-day teens used marijuana when they were in college, they often find it difficult to talk about marijuana with their children and to set strict ground rules against it. This conversation must begin early, as marijuana use today often starts at a young age—with more potent forms of the drug now available to these children and adolescents. Parents need to recognize that marijuana use is a serious threat, and they need to tell their children not to use it.
Q: What is marijuana? Aren't there different kinds?
Marijuana is a green, brown, or gray mixture of dried, shredded leaves, stems, seeds, and flowers of the hemp plant. You may hear marijuana called by street names such as pot, herb, weed, grass, boom, Mary Jane, gangster, or chronic. There are more than 200 slang terms for marijuana. Sinsemilla (sin-seh-me-yah; it’s a Spanish word), hashish (“hash” for short), and hash oil are stronger forms of marijuana. All forms of marijuana are mind-altering. In other words, they change how the brain works. They all contain THC (delta-9-tetrahydrocannabinol), the main active chemical in marijuana. They also contain more than 400 other chemicals. Marijuana’s effects on the user depend on it’s strength or potency, which is related to the amount of THC it contains(5). The THC content of marijuana has been increasing since the 1970s.
Q: How is marijuana used?
Marijuana is usually smoked as a cigarette (called a joint or a nail) or in a pipe or a bong. Recently, it has appeared in cigar wrappers called blunts, when it is often combined with another drug, such as crack cocaine.
Q: How long does marijuana stay in the user's body?
THC in marijuana is rapidly absorbed by fatty tissues in various organs. Generally, traces (metabolites) of THC can be detected by standard urine testing methods several days after a smoking session. However, in chronic heavy users, traces can sometimes be detected for weeks after they have stopped using marijuana.
Q: Why do young people use marijuana?
There are many reasons why some children and young teens start smoking marijuana. Many young people smoke marijuana because they see their brothers, sisters, friends, or even older family members using it. Some use marijuana because of peer pressure. Others may think it’s cool to use marijuana because they hear songs about it and see it on TV and in movies. Some teens may feel they need marijuana and other drugs to help them escape from problems at home, at school, or with friends. No matter how many shirts and caps you see printed with the marijuana leaf, or how many groups sing about it, remember this: You don’t have to use marijuana just because you think everybody else is doing it. Most teenagers do not use marijuana!
Q: What happens if you smoke marijuana?
The way the drug affects each person depends on many factors, including: - user's previous experience with the drug; - how strong the marijuana is (how much THC it has); - what the user expects to happen; - where the drug is used; - how it is taken; and - whether the user is drinking alcohol or using other drugs.
Some people feel nothing at all when they smoke marijuana. Others may feel relaxed or high. Sometimes marijuana makes users feel thirsty and very hungry—an effect called "the munchies." Some users can undergo bad effects from marijuana. They may suffer sudden feelings of anxiety and have paranoid thoughts. This is more likely to happen when a more potent variety of marijuana is used.
