Never going to stop using. I'm also impartial as to which substances i take, as I love pretty much all of them except benzos.
I don't seek out drugs very much. Don't even use all that often. But when i get a hook on something I buy as much as I can afford without a second thought. I'm pretty good at saving things.
A solid psychedelic experience 2-4 times a year just does something wonderful for my mind that goes beyond words and rational thought. Opiates are one of the standards by which I measure pleasure and satisfaction. I love these things, and would change as a person were they taken away forever. I generally go months between using, but to never use them again in my life would sadden me greatly.
I guess if it came down to it I could get by with alcohol, tobacco, and cannabis. Then again if it came down to it I could eat McDonalds every day. Doesn't mean I want to do either of those things, or that either of them are healthy for me.
Some people take pride in grounding themselves in reality; having never left it, they don't know what it truly is.
