People become non-functional when the levels of THC are so elevated.
I like the way you put it: legalize, regulate, and discourage, but if we're going to legalize, that means you have to regulate, but who are we discouraging? Is it youth? Also, we are educating adults about the use. As I said, a lot of people are self-medicating, whether it's for a painful condition or a psychological condition.
The other thing is, with the legalization is going to come the availability of oral compounds that they can take. Why should people be smoking this stuff and taking in all the products of combustion?
There's a big field ahead, and I think the government is dead right in proceeding with legalization because of the fact that it gives us an opportunity to educate.
