steroids = scare tactics for ratings.
nobody cared that the NFL has used steroids for 30+ years because they just don't talk about it. Players don't write snitch ass books on each other, and the league boots guys rarely and more likely for weed than gear.
steroids scare parents. so they watch the news. which means the media outlets sell ads at higher rates. So, they blow up the story, and everyone in college, then high school, starts doing it. they create the crisis, then they cover it and give themselves a pat on the back for being on the cutting edge of trend coverage. If they didn't talk about it, 99% of kids in america would just be ignorant of the subject, and wouldn't "KNOW" they had to use gear to be in the big leagues.
