Why add the tax part?
I’ll give on the tax part to get to decriminalization. It won’t be possible to avoid sales tax. We have already learned that in Colorado.
Funny, I know 3 Coloradans who have obtained medical marijuana cards. All of them are millionaires who got there through years of hard work. Now I have to wave off their offers when I visit. (I’m a lightweight, the stuff makes me faint.)
Treat it like beer. People are allowed to brew a certain number of gallons a year tax free. Should be able to home grow up to a certain amount tax free as well.
