Nothing glib about it. Do you support or oppose banning alcohol, under whose influence many have killed others?
Just be sure to fight for otc status for ALL drugs. No more scripts. No more age limits; it follows logically from the debate you are just itching for - after all, how dare the government infringe on societys right to self medicate with anything for any reason. But be careful what you ask for, you may get it.
BTW, if you save the lines from that argument in word you can cut and paste to save time when you do get someone to bite.
