Three points, all having to do with the societal impact of drug use:
- Though the actual affect the drugs have on our bodies and minds may be fully our own concern, there's a much more important question about what we do when we're ON the drugs. Clearly, the whole purpose of a drug (or any substance, for that matter) is to achieve an altered state of mind - and this state of mind, as we know has deleterious affects on our rational judgment. Thus the rather acceptable concern that users of drugs might affect society in some negative way (even setting drugs aside, consider drunk driving).
- Secondly, there's the affect on society caused by addicts who are seeking more drugs but cannot afford them. Inevitably this leads to a crime of some sort in order to obtain something that might be used to procure more drugs, thus perpetually continuing a cycle of crime and drug use.
- Finally, and this is one I'm actually surprised to be ambivalent about, there's the idea that...well if we're to adopt the perspective of a steadfast capitalist, then rampant drug use creates a society of lazy degenerates. Drug users are not seen as productive, they do not create, they do not 'give back' to society in any way, do not contribute. They consume, and their consumption takes a toll on society equal to what their potential contribution might have been had they done something 'more productive' with their time and money.
There are people who drink without driving drunk, there are people who smoke without stealing to do so, and there are people who do both and still hold a steady job!
Wouldn't it be so much simpler if all people of a certain type exhibited a characteristic that we could unquestionably condemn? Sounds a little like racism, doesn't it?
