Here's what you can expect with legalized weed. First, the shameless public use of it, primarily by blacks, who smoke it everywhere without a care in the world. You'll see people smoking pot all around you. The cops will look the other way.
Second, the proliferation of "vape and smoke" shops will manifest in every seedy strip mall in town, bringing with them associated loitering and crime.
I’m in Michigan frequently. They have an abundance of weed sellers. I’ve never noticed the odor of it burning. Even in the seediest of cities. In other states, vape retailers are already in every strip mall. Even in rural areas. I don’t see much change.
