LOL is right.
The libs want people to believe this BS but very few go to jail on simple MJ possession charge. That’s a damn summons because police don’t want to go through booking someone on this crap. Catch and release.
Now if they were being truthful, they would say that the real reason they are in jail is for warrants, and the dope was due to a search incident to arrest, that I would believe.
Maybe in your jurisdiction you just let casual users go but not where I live. They take them to jail and sometimes will offer diversion programs at their own expense.
