Although I think the medical benefits of Marijuana are overrated,I don't see any harm in using it to help make life a little more cheerful for someone who is unfortunate enough to be suffering from a debilitating disease. I smoked marijuana for 30 years and the only negative effects I got were a little fuddled and confused sometimes,a little forgetful at times,and I did tend to get dependant(though I did give it up eventually).So,for someone who is getting on in life,seriously ill,or terminally ill,I think it would be unnecessarily cruel to deny them the mild,and relatively harmless benefits of it.
