Did You Know...


1. The well-confirmed danger of smoking marijuana is lung damage and lung cancer. As examples:
1 joint = 5 cigarettes in terms of amount of carbon monoxide (CO) intake.
1 joint = 4 cigarettes in terms of amount of tar intake.
2 joints = 20 cigarettes in terms of microscopic damage to cells lining the airways.

1 joint per day leads to a greater chance of lung damage than regular cigarette smoking.

2. If you use marijuana over several years, it disrupts encoding of your long-term memory. It impairs biosynthesis of nucleic acids and proteins. 

3. Adult users report the following consequences: memory loss, less able to concentrate, lower motivation, less self-esteem, problems with relationships, problems with health, and problems with jobs and finances. If a woman who uses marijuana gets pregnant, it can cause include low birth weight and prematurity of her infant.

4. Very high doses of marijuana produce a toxic delirium (especially if eaten), which may lead to confusion, agitation, disorientation, loss of coordination, and hallucinations. There are few known deaths from overdoses. However, if someone took a dose that was 1000 times stronger than the dose that gets one “high,” it could poison you.

5. The active component of marijuana is THC. It is stored in the blood for several months in regular users. Withdrawal symptoms include the ones typical of other drugs, including difficulty concentrating, irritability, urges to use, difficulty sleeping, depression, vivid dreams, anger, headaches, sweating, coughing and decrease in appetite.

6. Effects of marijuana on coordination place users at risk for accidents. THC is found in the blood of more than 30% of fatally injured drivers.

7. Twelve questions to determine whether or not you are a marijuana addict are listed in information from Marijuana Anonymous (MA). An example of a question is this: Is it hard to imagine a life without marijuana?

8. Marijuana users do seek treatment. Most of those who seek marijuana cessation treatment are not currently using other drugs. The relapse rate among marijuana users (in other words, the number who go back to using marijuana) is the same as that for cigarette smokers, alcoholics and heroin addicts. Approximately 65% of users relapse by 3 months after they finish treatment.

9. Perhaps because of increase in the THC content of marijuana, and potential for anxiety attacks while using, emergency room visits related to marijuana use have increased by approximately 20% in recent years.
