Tax revenue will plummet, and the entire state-sponsored apparatus will collapse, which will lead to a re-criminalization of pot in the end
Sounds like wishful thinking. CA collects $100M/yr in medical mj taxes on $1B sales, despite patients being allowed to grow their own. The program has been in effect since 1997.
That is because the laws are in flux at the moment. One state is here, another state is there....and the Federal is completely different. The differences in the laws between OR and CA is a perfect example of this.
Gambling is another example. Aside from Vegas, areas that have legalized gambling are either not growing or are shrinking, driving some Casinos out of business.
The difference here is that anyone with a spot of sun and a pot can grow it.
