Animal studies have found that THC can damage the cells and tissues in the body that help protect against disease. When the immune cells are weakened you are more likely to get sick.


According to one study, marijuana use by teenagers who have prior antisocial problems can quickly lead to addiction (3). In addition, some frequent, heavy marijuana users develop ā??toleranceā? to its effects. This means they need larger and larger amounts of marijuana to get the same desired effects as they used to get from smaller amounts.

Marijuana produces immediate, temporary changes in thoughts, perceptions, and information processing. The cognitive process most clearly affected by marijuana is short-term memory. In laboratory studies, subjects under the influence of marijuana have no trouble remembering things they learned previously. However, they display diminished capacity to learn and recall new information
