OK so i just made this account to ask this question so please excuse if i?ve done anything wrong, i?ve done mdma capsules a few times in the past year and have never had an issue, but lately i?ve become aware of how fast my heart rate is when sober (90-100bpm resting) (i?m not sure if that?s something to worry about without the mdma) i?m wondering how at risk i am of heart attack or cardiac arrest or whatever when taking mdma and my heart rate increases even more? i just want to know so i?m not worried about it if i do drop and then start panicking -making my heart rate faster again. i?ve looked all over the internet for some kind of answer to this question but to no avail, can someone with actual medical experience please give me some advice? thankyou!
