You want to institutionalize the non mentally ill homeless?
Why?
Now it's true that many of the homeless are mentally ill, but far from all. Many are addicts, addicted to the legal drug ethanol, others are addicted to other illegal drugs. Very few of them exclusively to MJ. Most people can function sufficiently well to hold a job and provide for themselves, even though addicted to ethanol or MJ. As much as anyone can be said to be addicted to MJ, the medical jury is still out on that one, but even if the addiction is not direct, there does seem to be an addiction to the "buzz" one gets from MJ.. I wouldn't know though, I've only even smelled the stuff once, over 30 years ago, and it smelled like an alfalfa drying plant to me.
No! Only the mentally ill homeless.
