What are the short-term effects of marijuana use?
|
|
|
The short-term effects of marijuana include:
- problems with memory and learning;
- distorted perception (sights, sounds, time, touch);
- trouble with thinking and problem-solving;
- loss of coordination; and
- increased heart rate, anxiety.
These effects are even greater when other drugs are mixed with the marijuana; and users do not always know what drugs are given to them. |

| Does marijuana affect school, sports, or other activities? |
It can. Marijuana affects memory, judgment and perception. The drug can make you mess up in school, in sports or clubs, or with your friends. If you're high on marijuana, you are more likely to make stupid mistakes that could embarrass or even hurt you. If you use marijuana a lot, you could start to lose interest in how you look and how you're getting along at school or work.
Athletes could find their performance is off; timing, movements, and coordination are all affected by THC. Also, since marijuana use can affect thinking and judgment, users can forget to have safe sex and possibly expose themselves to HIV, the virus that causes AIDS. |
