The Feds do, and any state where it isn't legal. If you have 15 plants, that's 15 #s, that's 15 years Fed if they want. If you are growing dope, don't own anything. Asset forfeiture is the goal, Feds as well as states. States will bust you also if you are a dick when you get caught, and you will get caught if they want to. There is more squealing amongst dopers than in any population of ne-er do-wells.
Here’s my solution, and the dopers and libertarians on FR still vilified me.
1. Anyone who wants to grow mj for their own use, fine. A set number of plants allowed; here in OR I think it’s 5, which is enough to keep a person stoned out of their mind 24/7 probably for more than a year.
2. No selling it, no “giving away” or trading. Personal use only.
3. Dope sellers get the book thrown at them.
Voila. Free choice and no pushing it. I live in SW in a n area known to have “perfect climate” for mj growing, and I’ve seen what it does to people in many ways.
I have zero sympathy for mj growers nor their clients, as a business. If individuals could grow for their own use, as here, it’s up to them if they want to get stupid and crazy, or use “medicinally”, or whatever.
