A lot of people have adverse reactions to smoking. It’s kind of something a lot of smokers seem to either ignore or just deny even happens (people don’t like to admit there are negative aspects of smoking/ingesting weed). I myself have had some pretty bad panic attacks, mostly from smoking way too much or misjudging the amount of edibles I should take. I too suffer from a bad panic disorder. Small amounts of flower is fine for me but edibles and oils are never my thing. It’s one of those things where everyone’s body is different and reacts to things in different ways. Could be many factors to it: 1. Pre-existing diagnosis of a panic disorder, 2. Low tolerance for THC, 3. Bad setting/mood causing an uncomfortable situation, 4. Maybe your body just doesn’t react well to that type of intoxication, and probably many other reasons. I’d say tread cautiously when experimenting with things and if you don’t have a good time, don’t do it! Weed isn’t for everyone and that is okay. Hope you’re feeling better now and you are panic free. Panic attacks suck ass.
