Generally in many places you would only be put in jail if you possess medium/large amounts of drugs and/or the state can prove that you intended to distribute them.

Ordinary users often possess "medium" amounts of drugs, i.e. what might reasonably be a one month supply for an individual, which prosecutors will then claim proves intent to distribute, when it proves no more than that a user might prefer not to interact with drug dealers more than once a month.
They often even possess "large" amounts of drugs, when the drug dealer cuts the drug 1000:1 with whatever trash and then the cops want to charge you based on the amount of white powder you have instead of the amount of the actual drug.
The problem is that it's completely plausible for an ordinary user to have more of a drug for their own use than a dealer needs to sell at any given time. The dealer really only needs to have in their possession the amount being sold to the current user.
If amounts below that threshold aren't illegal then actual dealers could feasibly avoid having more than that amount. If amounts smaller than that are illegal then you're putting users in jail. You can't have it both ways.

Pharmacies, drug stores, convenience stores. The same places people buy bourbon and aspirin without having to worry that it's full of methanol or has been spiked with fentanyl or contains 5000mg when the last batch was 150mg.
