After doing some research and analysis about prop 19, I don't see how it puts more restrictions on anyone.
The 1 oz limit... that's in public. If you're not a dealer, what are you doing with more than one ounce on you in highly populated areas/schools whipping out for everyone to see? (Only places I can think of that someone would get caught by police)
If you're driving in your car to transport bud I could understand having more than an ounce, but you don't have to worry about dogs anymore because weed will be legal, so cops CANNOT use a search dog to find your bud. Just keep it in your glove compartment, or a backpack, and the cops can't search it, easy as that. (If you keep your registration in your glove box, don't put it there). Furthermore, if you are in the business of transporting around a good amount of bud, GET YOUR FUCKING CARD, prop 19 doesn't stop anything that 215 lets you do, so with a card you will be able to carry around at least a half pound, which you already can do.
If you happen to be a dealer, and are worrying about the prices dropping drastically, guess what... that means bulk will cost WAY less too, so your profits will remain unchanged. A massive amount of weed is not going to be available in super stores or gas stations for a long time. If you have a family business and you want your grand-kids to deal, then make your own weed corporation, it will be legal.
The allotted grow spot dilemma... Are you concerned that a 25 sqft area is too small? Well what's the current area that you can grow in... 0 sqft. How does this limit anything? Prop 19 doesn't do shit to prop 215 rights, so if you have a card you can grow up to 99 plants in certain counties.
What about the growers that are worried about business? Remember your first time growing... the bud may have been good, but you probably only got an ounce - two ounces per plant. That runs out, as you already know, very quickly. Not only that, but the bud you grow will still be way better than the bud your customer grew. And who do you think your customer is going to buy clones/seeds from? You'll basically become a mini dispensary.
In my opinion, prop 19 will lower the overall cost of bud, not too significantly, and people will definitely still buy from their dealers. Especially college/high school kids who can't buy it legally anyway. It will also put around a bunch of b buds for a few years, but then lots of people will get good at growing, and bud overall will be much much much much better. More good growers sharing tricks with each other + more technology for legal growing = Really dank buds that are easily accessible. If you consider yourself a stoner, and you want better bud in the future, then vote yes on prop 19.
