Is exercising on cocaine a bad idea?

[coffeeshroom2.0]

I'm no doctor but I would assume it's a horrible idea. My heart feels like it's gona jump out of my chest just sitting on a couch on coke. Surely exercise is just making you more heart attack prone.

Then again I read stories about bodybuilders in the 90's having a crack before the gym.

I use to use khat a lot a a few weeks out of a show and till up until the day of the comp, to get super dry and help with that last bit of stubborn bf.
