More rank ignorance. People take drugs for a huge variety of reasons, and anyway, who are you to say they shouldn't? Most of the harms you're so concerned about not "enabling" are related to the illegal status of the drugs: overdose on unpredictable product, property crime, health issues, needle sharing... all of these have everything to do with the criminalization of drug use.

Oh, but it's so simple, is it? People should just choose not to use drugs? Well, maybe to start, sure--but are you really going to tell the street-living guy with health issues, no money, and little social support that you expect him to have the strength to wean himself off a masive addiction before you'll give him any help?

Please. If you think that's a realistic approach, you are completely blind to human nature and human suffering. Strength has nothing to do with it. Or, everything, when you consider the strength it takes to continue living like this, day in and day out. Try a little empathy next time.
