If they can, as is the case with laws that just prohibit new sales, then the money just goes elsewhere, where it can be bought. That was proven by the quickly rescinded "sugary drink" tax that was instituted in Cook County Illinois. Retailers were hurting from loss of revenue, and over the county line, sales were booming.
Any point in California is only about a 5 hour drive to another state.
If they outright ban the product, people will accept the issues where they live, break the law, they will move, or they will change the laws.
When you get down to it, that's the only choices.
Did Prohibition teach these people anything? Apparently not.
Philly did this a few years back with those sugary drinks. Just across City Line Avenue, the cars were backed up outside the convenience stores every day, as all the stores on the City's side died.
I agree. People will just jump the state line and get what they want there.
So silly. Let the marketplace sort it out. Most people are smart enough to sort things out for themselves, and decide with their wallets.
