Alcohol is legal and I don’t have to worry about my neighbors still.
Without the current prohibition, there would be no need for these idiots to run a “drug den” out of their homes.
I don't know about that. For all practical purposes, marijuana is legal in California. All one needs is a ridiculously easy to obtain "prescription", and you can then buy marijuana from one of the hundreds (perhaps a thousand) of dispensaries located throughout CA. But, that has not really reduced the abundance of illicit marijuana sold in the state. The marijuana drug production, distribution and illicit retail sales in California is robust.
Because marijuana's price to weight ratio is so much greater than alcohol, it will always have a black-market, even in the face of absolute legalization. Why? Because people will certainly look to circumvent the licensing and taxation that will surely accompany full-blown legalization. An ounce of marijuana has a retail value between $200 to $500. An ounce of liquor has a retail value of a few dollars. See the difference?
There aren't many still left in America because it's very time consuming to distill liquor. It's very space consuming, and it doesn't have a very good return on investment. Marijuana doesn't require much space. It doesn't require a lot of time and it is ridiculously lucrative, even in states that have partial legalization.
