Does Marijuana Impair Cognition? Implications for Prop 19
Does Marijuana impair thinking?
Posted Oct 12, 2010
So, what is the take home message? There are clearly some situations that high smokers should avoid. DON’T DRIVE. Driving, especially in crowded metropolitan areas, requires quick reflexes. And driving under the influence is illegal under Prop 19. On the other hand, this one small study implies that there are no serious cognitive effects to getting high. OK, I am still unable to find any solid scientific evidence indicating that using marijuana for recreational purposes like listening to music at home is harmful. Then, YES or No on Prop 19? I guess in the end, each individual has to make that decision for themselves but based on the very limited scientific evidence that exists, I can find no health reason justifying criminalizing marijuana. And, in fact, Prop 19 is supported by Joycelyn Elders, United State Surgeon General (Ret.).
