I may not be in the right subreddit so I apologize ahead of time. My problem stems partially from a substance abuse issue and a lack of daily social interaction. I spend most of my time smoking weed and browsing reddit. I have friends and people to go out with but when I actually have someone whos not smoking weed with me and we're out I don't know how to have a conversation.

I try not to use weed as a crutch in social situations, but it's more over mostly how I socially interact. It's just not conducive for daily conversation.

tl;dr - How do I have an adult conversation?
