The main mind-altering (psychoactive) ingredient in marijuana is THC (delta-9-tetrahydrocannabinol). The amount of THC in the marijuana determines how strong its effects will be. Hashish is made by taking the resin from the leaves and flowers of the marijuana plant and pressing it into cakes or slabs.
Some immediate physical effects include a faster heartbeat and pulse rate, and a dry mouth and throat. Studies show impaired or reduced short-term memory, altered sense of time and a reduction in the ability to do things which require concentration, fast reactions and coordination.
Marijuana is made from the hemp plant, Cannabis sativa. The main psychoactive (mind-altering) chemical in marijuana is delta-9-tetrahydrocannabinol, or THC. For more information, see the Marijuana Research Report.

How can you tell if a friend is using?
Sometimes it’s difficult to tell unless you see the person using. There is a difference between using, abusing and feeling addicted. Marijuana is not physically addictive, but can become psychologically addictive. Signs of use can include:
- Decreased motivation
- Slowed reaction time
- Memory and learning decrease
- Distorted perception
- Cough, phlegm

- Hair and clothing smells of smoke
If marijuana controls your friend’s life, it’s a problem. Signs include:
