"possession with intent to use"
I think "possession with intent to use" should not be the business of the state. Period. The state does not prosecute adultery nor should it. The state should also not prosecute other altered states one might wish to indulge in.
Like, nobody wants to be addicted to cocaine. Drug abuse, like adultery, provides it's own self-embedded punishments, and I don't get why the state feels a need to get involved. Like, how to kick people when they are down: criminalize them for drug offenses. Addicts already feel enough shame.
There is, and always will be, a market for drugs. We can play at fighting it, making it illegal, calling it wrong, being morally superior, but whatever we do, there is, and always will be, a market for drugs. Let's accept it, understand it, tax it, and start helping its victims.
