Following your logic use of illegal tobacco should be a major societal problem then, since the price of cigarettes is largely taxes. Is it a massive crime problem, with tens of thousands killed and millions incarcerated?
Come on, I thought you were a man of logic and reason.
It is a major societal problem. Not only is lung /throat cancer from second hand smoke a big problem, but there is an up swing on addiction now that Vaping give more a dose than reg cigs, and kids are far more addicted to it. They call it JUULing

The way to handle it, is get to the root causes of the problem.
And if Big Tobacco takes over the drug trade...
Police forces have noticed that in places where say marijuana is legal, the dealers are still present, because the dispensaries and supplies all have to pay taxes on the product. Which raises the prices on the product, the illegal dealer doesn't pay taxes, which means the product is cheaper.
And if you look at the fentanyl situation---where dealers are cutting their heroin with fentanyl, the people who OD and get brought back, want more, and so do the people who are addicts and witness it. So, where would a person get said product in a legalized drug situation? Well, the dealer, that is who.
