For those who drink alcohol, smoke and drink coffee those are drugs no matter how infrequently you do it. Then for those who do it often enough, stop for a month or two cold turkey, I dare ya!
Back to the question, I think I'd do it if it was under the right circumstances, under supervision of a doctor (not a guy who works for a doctor or a personal trainer type). Then I'd always get a 2nd opinion and test things out. This would also be if the Team supported it, I'd hate to be caught and be totally on the outside of the financial backers. If I didn't need it as in not pressured to win or be up at the front all the time past my abilities, I'd pass on it. If the management wanted me to, to support the leader and take on a heavier work load then I'd sign on, of course with a pay increase. Can't risk it and not have a safety net, as in life/contract insurance (if possible), record the management somehow when they asked me to or delivered product. Pictures as well of the stuff and anyone involved.
If caught I'd own up and do the time (unless the management was going to deal with the PR on the matter) and get the management to pay the fines.
I can see why the riders do it and I can also see how they don't fear the UCI nor bans, if they play it right they come back as if nothing happened. Those who don't play it right end up on the black list.
It would be nice if it wasn't needed but we have the reality of the matter...
