If marijuana were to trigger me to experience angina symptoms, would it also be triggered by other things like physical exertion or acute stress?

See doctor: Sounds like you're worried about chest pain or or other cardiac symptoms from marijuana, physical exertion and stress. You should be seen without delay by your pcp for an evaluation to determine how your heart is reacting to these factors. Meantime, avoid smoking mj or overdoing any physical activity. Tell your doc about any major stress going on. I hope this helps. Best wishes.
