No time to do justice to this topic, but David Pinto has a link to a fascinating and controversial piece on steroids in baseball:

Quinn is a second-generation disinformation artist. He takes his cue from a much younger Armen Keteyian who was largely responsible for beginning the late-20th hysteria about steroids some 20 years ago in his article written as a sordid eulogy for ex-NFLer Lyle Alzado. And almost 20 years after his screed he sat in front of Dr. Fost and apologized for being an accidental progenitor of the same type of disinformation Quinn - and those who do the same as him - spreads today. Almost 20 years later Keteyian sat in front of virulent anti-steroids buff, Gary Wadler, formerly of the world Anti-Doping Agency (WADA), and found that Wadler had no scientific evidence to back his claims that steroids were the evil he claimed they were; found that Wadler had no idea that Fost’s work existed. Sadly, Wadler was reduced to pathetic phrases like, you’re playing Russian roulette with your health, and why would you take a chance using them even if they aren’t harmful?

Here we are, with scientific evidence before us in the way of a peer-reviewed study that clearly shows that steroids taken under a physician’s care have no deleterious effects on healthy males over the age of 25 and that every male, because of a natural reduction in the amount of testosterone produced by the body, should take monthly injections of steroids to lead a healthier life - and the study is shunned like an “amulet” - that was actually nothing more than a pendant - might have been during the Salem witch trials.

Also, see this post from the same blogger. It is too long and good to excerpt, but anyone interested in the historical context of drug policy needs to read this.
