Other aspects of why drugs suck is because of the types of people involved, and perhaps where the drugs come from, which could be moral dilemmas. If you buy weed from someone who grows it in their shed, okay I don't see a problem with that. But dealing with thugs and lowlives and debt-collectors, that's just not the way to go, and those people shouldn't make money in my opinion.
Yeah, that is one important issue. If you aren't growing your own drugs or getting directly from growers, that's a big problem. The drug industry is violent, and by buying drugs, you are supporting that violence.
My friend had a girlfriend who was rather conservative and was very hostile to certain types of people, "criminals" being among them. Yet she did drugs. Not heavily, but she dabbled in a variety of them. I found it highly hypocritical that she would be so mean-spirited (a 'lock them up forever, or why not just kill them' mentality) towards violent offenders when she was supporting them and their activities when she bought drugs. I don't think she made the connection whatsoever.
Funny, it's kind of like how people don't make the connection between walking into a McDonalds to buy a burger and the factory farms and the slaughter and all that. Like how people will say they could never kill an animal but have no problem requiring that other people do it for them.
Anyway, back to the drug issue--I don't think I thought about it much when I was younger and smoking pot. And, being right near Woodstock, most of the pot we got actually was grown in personal stashes. But that doesn't excuse it, either, because where did those people get their seeds to get started? It's all tied together. Anyway, now I am aware of these issues. I mean, people are murdered and tortured and have their lives ruined because of the drug trade. I couldn't support that.
And yes, one can argue that these acts of violence occur because drugs are illegal and that legalization could put and end to that. But the point is that they are illegal right now, so if one buys drugs now, that's what one is supporting.
