Not to belabor the point but in California the laws were changed to get the non trafficker into drug treatment programs. You have to get caught many times before a non trafficker goes to jail.
That's not working either.

The key is social acceptance. We can't promote a culture of drug acceptance and then expect societies members to avoid it.

I am all for treatment, it saved my life, but adding social acceptance to a problem does not make the problem go away.

If we made murder legal, would murders stop. A reasonable person could conclude that murders would increase not decrease. The same is true of all socially unacceptable behavior.
Remember a surge in decadence amongst Roman citizenry was soon followed by the collapse of their entire civilization. In a society where anything goes the next to go is civilization itself.

The answer to your question about MR. M16 going to jail, he says it saved his life. No theory just his experience.
He no longer uses, is successful in his business and is/has been reunited with his family for many years now.
Identifying the problem is the addicts biggest hurdle when it comes to recovery and jail can really turn a light on.
