no, it cant cause heart problems.... studies have shown that MJ actually stimulates the cardiovascular system

carcinogens, yes, any time you inhale smoke you will have them... but it isn't that bad for you. if you live in a major metro area, you inhale about a pack and a half (cigs) equivalent in carcinogens daily... nicotine is the prime cancer causing agent... w/o the nicotine, your lungs just expel all that nasty shit with little to no adverse health effects, highly variant on the individual ... your lungs can handle that shit easily, this is why everyone in the city doesn't get lung cancer :twocents:

overall, mj is pretty good for you, minus the burning plant matter part
mightymarijuanabuds Reviewed by mightymarijuanabuds on . Does weed cause heart problems? I have been smoking for 2 years and a bit, and i was wondering if weed, actually contains the same heart problems agents as ciggarettes do. Sometimes after i hit up a huge sess, my heart aches, its not like a sharp pian, but rather an ache, like you'd get in your stomach, any idea what could be causing this? Probably lack of oxygen circulating the the heart(oh wait, can't that turn into a heart attack?) Rating: 5
