This is where it gets complicated. Tons of people do cocaine, and it often gets coupled with activities like dancing and people don't just drop dead. However you see a lot of coke users dying of heart attacks in their 50s (compared to users of other drugs). I think it's really hard for humans to accurately calculate risks (myself included).So it would be bad to take cocaine and then play tennis?

, then 250mg ones and all type of "vehicles" in between
), LSD and 80% pure racemic amphetamine, that we were overdoing from the get go...90s kicked ass, and thar particular Monday I was crashing heavily. I remember that I asked my mom to go with me to ER cause my heart was pounding so hard that I was too scared to go alone. Even just standing up to fast made me blind for more than a minute. I got to the ER, had EKG, cardiologist listened to my heart and concludedthat "This kind of things happen...when a person is anxious cause of missing school, has panic attacks and 'becomes too aware of his heart'. But you have nothing to worry about cause you have very strong heart that is beating regularly. You have what is referred to as 'an athletes heart' and dont have to worry about a thing.". My heart rate was apparently in the 50s and my blood pressure was perfectly normal. I guess all those trainings and running all my childhood gave me some extra space. As soon as I found out that all the tests came back perfectly fine I started to daydream about Wednesday and Drum&Bass party that was next on the menu. Now, almost 30 years later I am just thankful that all those "party drugs" and very hot venues that I religiously attended 4 times every week didnt do me in then. I still have heart that is not missing beats or going above 60 if I am resting. But man was I lucky to live in every sense of that statement. Nowdays it is only festivals and chill music for me. Days of youthful glory are way behind me and I am intent to live at least another 30 years. It was a rant but the point is - heart rate is not the best indicator of stimulant overdose. Body temperature and hydration are the things to look out. And not doing stupid doses and combinations like I unfortunately did in my teens. Take care everyone and look after your body. It is the only one you have so treat it with the respect it deserves. Nighty night...
