Weed can trigger panic attacks in people. I am 32 years old and have suffered from panic disorder for 14 years. It *****. I know marjuana triggered my first panic attack, and I smoked it for years after that not realizing I was making it worse. Do not smoke any more weed, and see if you have any more panic attacks (that is definitely what is happening) If you have another one, have your mom take you to the doctor to get you some sort of treatment. Good luck.
Stay off weed. The only thing weed affects is your mental health so it is a big problem. It sounds like you've built up a dependence on it. Go to a doctor and stop smoking weed.
