HAHAHAHAHA, what an idiot. How about we just decriminalize cocaine possession/use, and have a mob of buzzed up people shooting people and vandalizing things. If the government doesen't get involved these things will happen.

His grandfather killed himself, but its not the governments job to sit around and ignore various health risks to society. Theres no way anyone is going to ban cigarrettes, but taxing them heavily will deter some people from using them. Funding research about prevention is intervention is also another way government can get involved.
