My former boss (Canada) kept a bag of ephedrine bottles in our produce cooler. Dude was twitchy as fuck. Very bird/dinosaur-like.
He would take several per day and chase them with coffee and energy shots. Then he would complain intermittently about vomiting blood due to his ulcers.
I just view the person giving it as trashy. They're like a living Kid Rock album. So bad-ass.
