Those functions exist. They are culture and adulthood.
I'm not being glib here. I'm not a crack addict because as an adult I can recognize even trying that drug is a really bad idea, and because I exist in a culture where doing crack is not encouraged, to say the least.
I appreciate the comment. But if those were enough deterrent for everyone, why do we have any drug addicts at all?
This is an incremental lowering of the barriers to people getting involved with hard drugs, and I cannot imagine that it will not produce some incremental outcome of people getting addicted compared to before.
