I'm smoking weed for the first time in a year and a half tomorrow night.

That was the last time I smoked real weed ( I was pretty regular before this). I vaped some "CBD" in between now and then but it turned out to be synthetic morphine, so I stopped completely after I found out (about 3 months).. It was the most intense highs I've ever had and not in the best of ways....Anyway, I took a break from drugs in general to get my mind back in the right place. It's not exactly there yet, but I'm in a lot of physical pain and I want to use weed to help manage that. I guess I'm just looking for words of encouragement and maybe some advice for someone tripping after a year and a half of not. Maybe some song or activity suggestions too. Thank you guys and much Love!
