Hello everyone, I'm finally thinking of trying mdma(ecstasy), but when I knew that it has effects on the heart beats, i started reconsidering my decision, because sometimes I feel that my heart beat are very strong and fast, and sometimes i have like 2 very strong beats in a row that i feel like i'm tired (like i've been running ) for like 2 secons then it's gone , I have not visited a doctor but I think it's called "heart murmur", anyway I would like to know if ecstasy would affect this, and is it dangerous ? i'm not taking any medicine BTW, and i've been advised to start with half a pill
thanks
thanks
