If marijuana truly has no lasting side effects, why is it so widely thought to be a harmful drug? I have a hard time believing that all of the sudden it is perfectly fine to smoke.
Also, this may be just my personal experience, but my old best friends brother started smoking marijuana, which lead to other drugs, and now his life is literally ruined. He was kicked out because he started threatening his parents, stole from them, and is probably suicidal now.
