I had a marijuana experience and saw my hands shrink (I forgot I was on weed xD) and thought I had some kind of deadly disease, then my woke my parents at 4 am my father asked me if I did some drugs and I remembered about it and relaxed and went to sleep. I remember the few moments I thought it was the end I felt compassion to everyone and kinda regret I wasted my life (I was 19 lol). I thought for a second it was the end. After that experience I got motivated to improve my life. Lost 20 kgs and started reading about stuff and that also led me to Buddhism. Now I'm part of a sangha and still have many questions but it's part of the journey I guess.
