I have no right to use force against them. I just don't see how any intelligent human being can fail to grasp the difference between discouraging something and criminalizing it. It's not healthy. You're going to get cancer and rot your brain. It's rude, crude, disgusting, impolite, and makes you look like Keith Richards.
Criminalization is entirely orthagonal to discouragement.
The people at the bottom get burned, and the scum floats to the top.
