So with this logic, things that are at least slightly harmful short-term or long-term to humans include:

- Any pharmaceutical compound that has the potential for dependence or addiction such as opiates
- Alcohol, tobacco, and caffeine
- Cars, due to the carbon monoxide and nitrogen oxides they emit.
- Generally unhealthy foods such as most fast food items, ice cream, etc.

As you can see, banning things like these are ridiculous considering their economical and ethical ramifications. A government needs to allow a certain amount of autonomy for its citizens.
