There are natural consequences and artificial ones.
Saying that jail is a "natural" consequence of drug use is a lie. It is an artificial consequence made real by evil actions committed by sick people. The natural consequences of drug abuse (note: not use) can be horrific. But there is no justifiable reason to heap artificial consequences on top of the natural ones.
You don't "help" a person by caging them, stealing their money and other property, by making them lose their job, and by alienating them and their family. Only a truly sick individual would see that as "helping" them.
An honest drug warrior would acknowledge that it is all about punishment. But that is also evil. You can't be a decent human being while punishing people for harming themselves. And don't forget, almost ALL the negative consequences of drug use have nothing whatsoever to do with the drugs, but everything to do with prohibition. Drug users (and abusers) who manage to avoid detection by the authoriturds generally live productive lives due to the absence of the life-destroying artificial consequences. And even if they do destroy themselves, that is their right.
If someone's actions harm another person or their property, then it makes zero difference if they are "on drugs" or not. Stop pretending otherwise.
