The harm done by drugs is not just to the poor, weak-minded druggie. The harm is to the rest of us as well. We're right not to want it legal as we're forced to bear the burden of drugs and its consequences.
Nationwide "54% favor marijuana legalization": http://www.people-press.org/2014/04/02/americas-new-drug-policy-landscape/
It's been 13 months since a poll showed American favoring the legalization of pot. That seems to confirm my point that historically Americans have objected.
What are you trying to say here - that to you "historically" means less than 13 months ago? And is there evidence that things have changed in those 13 months?

Society has through its elected representatives chosen to create programs through which this burdening takes place. The conservative position is to end such rights-violating welfare/redistributive programs, not to use them as an excuse for still more rights-violating policies like drug criminalization.
