Marijuana overactivates parts of the brain that contain the highest number of these receptors. This causes the "high" that people feel. Other effects include: altered senses (for example, seeing brighter colors) altered sense of time changes in mood impaired body movement difficulty with thinking and problem-solving impaired memory hallucinations (when taken in high doses) delusions (when taken in high doses) psychosis (when taken in high doses) long-term effects marijuana also affects brain development. When people begin using marijuana as teenagers, the drug may impair thinking, memory, and learning functions and affect how the brain builds connections between the areas necessary for these functions. Researchers are still studying how long marijuana's effects last and whether some changes may be permanent. For example, a study from new zealand conducted in part by researchers at duke university showed that people who started smoking marijuana heavily in their teens and had an ongoing marijuana use disorder lost an average of 8 iq points between ages 13 and 38. The lost mental abilities didn't fully return in those who quit marijuana as adults. Those who started smoking marijuana as adults didn't show notable iq declines.
