re: I just had a colonoscopy this morning with Propofol, and damn that is one powerful drug

Not aware that Propofol induced euphoria. Used it a lot for peds sedation, the stuff works fast, but also dissipates fast. Great for quick procedures like a CT or MRI but had to watch their respiratory rate like a hawk, does not take much to stop their breathing.

I am not aware that Propofol causes a euphoric high, I thought Michael Jackson used Propofol to sleep.
