Marijuana is not a harmless little plant. Marijuana can cause changes to your brain and it contains the same cancer-causing chemicals as tobacco.¹ It can also ruin your future, by getting you kicked out of school or off a sports team, or get you in trouble with the law. You call that harmless? And besides, the fact that something is 100 percent natural doesn't mean it's good for you. Heroin is synthesized from a chemical produced by the opium poppy. Cocaine is extracted and refined from the coca plant. These are two of the most harmful drugs known today.

Research proves that marijuana is addictive.² It's true that withdrawal might not be as severe as with heroin or other drugs, but research shows that people who regularly smoke marijuana have withdrawal symptoms-drug cravings, decreased appetite, nervousness, irritability, stomach pain, aggression, and anxiety, among others.³

Marijuana affects the skills needed for safe driving: alertness, the ability to concentrate, coordination and reaction time. A study of patients in a shock-trauma unit who had been in traffic crashes found that 15 percent of those who had been driving a car or motorcycle had been smoking marijuana, and another 17 percent had both THC (the active ingredient in marijuana) and alcohol in their blood.⁴

Marijuana contains the same cancer-causing chemicals as tobacco-including the deadly carcinogen benzopyrene-and at higher concentrations. Smoking five joints a week is the equivalent of smoking an entire pack of cigarettes every day which, even in the short term, leads to lung and respiratory problems. Long-term use increases the chances of tissue damage and lung cancer. Regardless of the content of THC (the intoxicating chemical in marijuana) the smoke inhaled by users contains three to five times more tar than cigarette smoke. A study conducted at the University of California, Los Angeles shows that the way smokers inhale marijuana and hold it in the lungs adds to the damage.⁵

Can impair judgment and make a person more likely to get into trouble The popular stereotype of the pot user is the "mellow" label. The facts don't support this image. Smoking dope can lead to anxiety, panic attacks, depression, and paranoia.⁶ Teens who become regular marijuana users are three times as likely to have suicidal thoughts than those who don't, according to the National Household Survey on Drug Abuse.⁷ The Household Survey also found that teens who frequently use marijuana are almost four times as likely to commit a violent act-either against people or property-than those who don't. They're five times as likely to steal.⁸

Even after users stop feeling the effects of marijuana, the drug can linger in the body for a few weeks. That means it can be detected by a standard drug test long after its initial use.⁹
