Mike,
From what I understand about that drug only one moment of lack of judgement or a wrong decision can ruin anyone that even tries it ONE time.
I know a police officer here that got on it and it destroyed him. He was like 6'6" and weighed something in the neighborhood of 285 pounds.
When he was arrested he weighed 140 on the dot.
He told them, "Thank God." when they put the cuffs on him.
Said he hadn't slept in 9 days.
Very very sad and I sincerely hope if he did get on Meth, he can indeed get off of it.
From what I have heard the chances of that are slim though. (Getting off of it I mean)
Sad all the way around.
