Does Marijuana Cause Brain Damage?

Brain damage is a major issue that marijuana prohibitionists point out as a primary reason to ban cannabis. Throughout the "Drug War" declared by then President Nixon in 1971, which has been continued through subsequent presidential administrations, there have been a few outrageous attempts at proving brain damage from cannabis. However, anecdotal and clinical application reports of recoveries from brain damage or neurological diseases have contradicted what most formally funded academic studies report regarding effects on the brain. Studies not funded by American government agencies, however, are reporting that the brain damage fears are at least exaggerated, if not completely unfounded.
