your views are very well balanced and i appreciate that - i get so used to stoners telling me how it is a healthy product and does no harm - addiction is a problem whatever the substance and i think this whole medial marijuana thing is going too far in support of a drug that does a lot of harm to those with mental health issues
anything can be used helpfully or harmfully. ALOT of good can come from its legalization - though that doesn't mean it wouldn't be beneficial to educate on the boundaries between use and abuse. prohibition doesn't stop abuse any more than legalization does. though at least as society starts integrating, regulating, and educating about it, the potential to abuse goes down as the awareness generally goes up about the differences...
I agree that is why we say never over do anything just keep it balance.
