I'm not gonna lie.
When I do drugs, I do them for one reason: Because I enjoy it.
It's the same reason I play video games or build sandcastles or draw: I enjoy those things, so I do them.
When I first started doing marijuana, I did it to help me cope with my depression. Then I started therapy, got support, and worked through it. I still get depressed for about an average 3-5 months out of the year, but now I have support and coping skills to make it through. But I still do pot (when I can afford it) because I enjoy it.
In my view, it's not wrong unless I'm hurting someone else. I should be free to do with my own body as I please as long as it doesn't harm others. But that brings me to my next story: How I learned to not get high and drive.
I once got pretty decently stoned, then got a call from a friend that he had broken down about one third of a mile from my house. So I hopped in my car to go get him. After I picked him up, I was crossing the highway when I zoned out and got confused about which road I was on. I then started to pull into oncoming traffic. If he hadn't been sober and started yelling at me that I was going the wrong way, I'd probably be dead or severely injured right now. From that moment onwards, I've refused to drive if I've smoked within the previous 6-8 hours.
That's a lot of the reason why I'm pro-legalization, but with restrictions similar to and punishments harsher than those for alcohol.
I see it as: The guy who sits in a bar at home or in his house and gets drunk but doesn't harm anyone other than himself is fine, but the asshole who gets drunk and starts picking fights or driving or hits his wife or neglects his kids should be punished in some way.
My apologies for the wall of text.
