Is it authoritarian to ban a dangerous product which is killing people? Who pays the medical bill when these people die? These poisons should have been taken off the market 50 years ago. Once the Surgeon General's Report was released.
Tobacco is a product that has no useful purpose other than to addict, sicken and kill people. But the Tobacco Industry employed thousands of people in the 1960's, and make the tobacco companies very rich, as well as tobacco farmers, and just like the gun lobby, the government does nothing to stop them.
The US government will let you kill people with impunity if Big Business can make enough money and employ enough people doing it. And they will protect your right to murder citizens if you donate enough money to their campaigns. Just ask Big Pharma about the ongoing opiod crisis.
You have little to no understanding the meaning of "authoritarianism".
