I have voted "yes", but there are nuances. "Legalization" does not have to mean that hard drugs can be sold like candies. Rather, it should mean that the ever-lucrative business of recreational narcotics is taken away from the criminals and conducted in a safe (in comparison with the status quo), limited and regulated manner, from marijuana being treated the same way as alcohol to an equivalent of Victorian "opium dens" for hard-drug users.
And by the way - neither I nor any other libertarians I know personally do drugs. Some of them don't even drink.
