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.
Any speeding offense with a child in the car can be prosecuted as a criminal offense.
Being 31 days late in filing your taxes can be prosecuted as a felony.
Every bounced $20 check can be indicted as federal bank fraud.
Every controlled substance you've been prescribed, which is beyond the "discard after" date on the label are now illegally possessed drugs, subject to prosecution.
In reality none of these things happen.
Go to any cannabis focused forum and you'll find no shortage of these who've had run ins with the law over the substance, including imprisonment.
Go to something as wholesome as a hunting and fishing forum and you'll even find plenty who've had to go to court to defend various charges.
How many here, one of the highest concentrations of PED experienced users in the country, have gotten into legal trouble for possession of steroids in the US? 100? 10? How about .a few, at least? None. Or they're all "deep undercover", terribly scared to tell their stories.
Do I need to mention the tens of thousands of shipments seized at the border that universally result in no action taken against end users as a pretty good proxy for government's attitude toward enforcement?
When "kingpins" of multi state steroid distribution operations, investigated for years at a cost of millions, who import foreign precursors, and coordinate manufacturing operations are sentenced, the absolute pinnacle of AAS related crime, they get, at most, similar sentences to repeat drunk drivers. All those lower in the organization. get probation, or deferred adjudication, or not prosecuted at all.
Now I'm not suggesting anyone brazenly flaunt their possession of an illegal substance, but the idea that in light of all we see, users should cower in fear, avoiding. "stocking up" because prosecutors are just waiting to leap on them with "possession with intent to distribute" charges is absolutely absurd.
