This legalization attached with a 75% tax is a huge windfall for every cartel and gang in America. And what can the police do? How can they verify that every ounce a person holds was purchase from a registered store? Impossible! And now when Mexican gangs do get caught all they are charged with is not having a proper license.
This kind of rhetoric is essentially talking out of your ass.
The key to this is that people can pretty much get high and still work in these states and still be a smoker. Weed has always and will always be more than corn and potatoes and either the cartels, the government will always have control of any vice unless you make your own.
The only ones that really lose with legalization are the dealers. As long as you are not a dealer enjoy your new freedom and quit bitching. A lot of us just like to get high, not use it as a way to make money.
