Hi. I am a 55yr old male,smoked good pot for 40 of em. Just had open heart surgery to replace my aortic valve. Its 3 wks after surgery and I feel super. I am slim and in great shape-no other health probs.However........my cardiac doctor would have me believe that if i resume smoking pot (and I told him I`m a very light user) that it would almost certainly trigger a heart attack. Does anyone here have a good objective input on this? Love to hear from ya. Hate the idea of givin up weed!
