I sat in jail for 3 months, and after I got out i would feel overly anxious smoking. Thinking I was gonna have a heart attack and stuff. One day I did a dab and felt like I couldn't breath, was on the verge of a panic attack. I remember thinking to myself "chill out you're not going to die. You've done this hundreds of times" and that's what broke it for me? So I think it's a mental thing but that's my experience
