Chest pains and low blood pressure due to substance abuse , sorry someone i knew tried mdma , and two days later is experiencing typical symptoms of low blood pressure and tightness in the chest (moderate). having previously experimented with amphetamines, this same person visited the doctor with tightness of the chest, and was told this was anxiety induced by overuse of said intoxicant and would pass in time (which it did). this someone would like to know if the present symptoms - tightness in chest, dizziness especially when stood up, feeling slightly faint, lethargy - may also be down to anxiety (which he appears to be predisposed to), and would like reassurance that they too will pass. this someone apologises for the idiocy displayed in making the same mistake twice, and for wasting your time when you could be answering questions posed by responsible people. thanks
