I understand the point that Dhue is trying to make, but I think she's wandering way out of her true area of expertise.

First of all, I don't think we even know yet with certainty exactly what drugs Armstrong was taking. Secondly, I'm not aware of any research showing that things like HGH and the types of testosterone-boosters that most athletes typically take are "addictive". Comparing them to excessive use of alcohol strikes me as misleading and fallacious.

I wonder...did Armstrong take these drugs continuously? Or only in the run up to big races.

If Armstrong was able to abstain from use when not racing (and to pass drug tests), I wouldn’t exactly say he was addicted to the drugs. Rather, I’d say he was addicted to winning.
