Marijuana, it's been a controversial issue whether long term marijuana or cannabis use causes brain damage. There can be some acute affects of decreased coordination, some slowing down of psychological processes or we call cognitive problems, but these seem to go away after the active ingredients of cannabis are out of the body. I don't believe there's are any good studies that shows that use of just marijuana over any period of time produces any brain damage. Part of the problem though is that very few people use just one drug so they may drink along with cannabis use or they may use other drugs and those drugs may be causing long term brain damage. Certainly we know that about alcohol that it can cause dementia, or psychosis a number of problems over the long term. But marijuana alone, where it's been studied is not associated with permanent brain damage.
