Me and a buddy are planning to open a smoke shop if it ever becomes legal, kinda like Amsterdam has, a selection of premium stuff for people of the legal age to enjoy. There'd still be a market for pot; not everyone wants to grow, just like not everyone grows their own veggies or makes their own beer. They *could* but it's a hassle. Doing it for them, providing that service, along with providing a nice peaceful setting to enjoy their vice, that's how we'd make our money.
