Craig was addicted to a lot more than steroids.
A lot of people I know tell me drugs are so hard to get over, and that may be true from their own subjective perception. Opiates are the hardest, no doubt. How would I deal with withdrawal? My genetics are too good to even get addicted to begin with, but if I were to, I'm sure I would handle the withdrawal as best as it could possibly be handled. Physiologically, it would be impossible to deal with it with ease, but I think I could handle it as well as any human being could. I know people who are addicted, and without question, there is a big variance in how well the addiction and withdrawal is handled, and handling it improperly is a reflection of poorer genetics.
Someone I know who was using three oxycontin-80's daily managed to do the cold turkey withdrawal in jail and did it! He is the much better person for it now.
What I mean about weak genetics are these people who are forced to go off cold turkey in jail and once they have withdrawn completely, they go back on as many opiates as before! Sure, it's not that they chose that, sure, they weren't able to stop themselves, but you know something? Having those qualities are a sign of bad genetics, plain and simple.
I empathize with drug abusers somewhat, but if they were so selfish and self righteous most of the time, I could probably feel sorry for them.
