"Something irritates me so I want the irritant taken away and locked in a cage". Your vision of the world is clouded by your own hate. As you are someone who conflates a plant with 'drugs', I strongly recommend you spend some time to understand the issues, understand the really nasty history behind prohibition.

Stop and think about how your attitude is trapping humanity in a box. Live a little. Be open to change. Understand others perspective.

All the same, they should not be subjected to the smell of smoke from their neighbors house.

I should not be subjected to the smell of my neighbor's cooking, but here we are.

An important part of living in a civilized world is to put up with the merely annoying stuff our neighbors do. After all, the odds are good that you and I do at least one thing that annoys our neighbors as well.

Would you stop BBQing if your neighbour complained about it?

That's an interesting question. If someone had a smoker running all day, everyday, and it was an annoyance to neighbors - yes, I think there should be recourse.

One person shouldn't be allowed to harm other people's enjoyment of their property.

As someone who was vegan/vegetarian for many years, the smell of bbq used to make me ill. (I only eat meat now).

Only a self absorbed busybody loser jerk with nothing better to do would complain about the neighbors bbq'ing. 'get a life'.

Really? Someone shouldn't be able to smoke in their own house/property?

Different folks have different motivations.

Capitalists want to legalize for profit.

SJWs want to legalize to reduce the prison population.

Libertarians want to legalize because one should be free to choose what they do with their bodies.

Users want to legalize because they don't want to deal with the risk, and prefer above-board retail.

Your characterization of smoking as a "vice" is your personal belief, and personally speaking, I see forcing that belief on others as a vice.

You're missing that legalization breaks criminal monopolies, let's people get help more easily if they need it, and removed a mechanism where law enforcement can basically make someone or some group they don't like a criminal, by making illegal something that most people do.

Actually I think restricting what adults can do to their own bodies goes against "progress for humanity."

So you would prefer people be locked in cells for what they do to their own bodies? How far would you like to take this line of thinking, for the "progress of humanity"?
