I agree. But if you are smoking next to me, now I am too.

It should be illegal to affect anyone by the smoke.

My dream system would be: If you are at a public place but there is no one else around (clearly defined by distance), that would be okay. If there's a single person they would have right to sue you and it's your responsibility to ensure you aren't affecting anyone as the smoker. If in doubt, you can smoke home.

My point is, anyone should be able to anything to their own body as long as their actions aren't affecting other people. Anything from smoking/secondhand smoke to harder drugs/driving under influence etc would be judged by the same logic.

I don't smoke and actually hate smoke, but I don't feel that I have any right to prevent anyone from smoking, as long as their smoke doesn't get in contact with me.

What if my taxes are paying for their healthcare? (I don't support completely banning smoking, but just playing devil's advocate here)

What if a billionaire smoker pays for your healthcare the most? I think it's completely fair for that billionaire to also mandate that you must smoke.

Then he can lobby it (and probably fail).

The system is wrong. Everybody should be paying for their own healthcare OR if there will be public healthcare, people who are at higher risk due to their own actions (like smoking) should not be covered by healthcare/pay an extra to be covered etc.

I definitely agree with you on someone shouldn't be paying for someone else's healthcare.
