Still waiting for evidence of him being prosecuted for "steroid possession".
Nonetheless, charges for possession do happen, at around the same rate as being struck by lightening. Convictions for possession are so rare no one can find an example without going back years. And imprisonment is non existent. This in the context of an estimated 4 million steroid users. FOUR MILLION.
Convictions are rare? If by that you mean plea deals are not a conviction or there is a pretrial diversion, you are wrong on the first count and not wrong on the second, but not every court system has pretrial diversion. Moreover, it had better be a first offense. In the state to the south of you, a first offense, possession only, Schedule III, is 1 to 3 years. A third offense is 1 to 5. Most of the counties in the state to the south of you have a pretrial diversion program available (not all of them) but you must have never had a drug offense, ever, in your whole life, to take advantage of that. Small amount of pot possession charge back when you were 17? No pretrial diversion for you.
You will, however, even if you get pretrial diversion or a conditional release, lose your license to drive for 6 months. Second drug offenses are a year. Third are two years.
Then there are all sorts of other considerations, like professional licensing.
They removed the disability for student aid, so at least that is no longer a concern.
Even just the indictment, without any conviction, removes your ability to purchase a gun (if you try, that is a separate federal felony).
STRUCK BY LIGHTNING?
The odds of being struck by lightning are 1/1,222,000/yr
Odds of being charged with possession of steroids are probably higher than that.
You cannot rely on news stories to determine this - minor drug possession felonies are not newsworthy unless they catch 5 cops in the local department with steroids.
