I don't disagree but what right do you think would be violated with precision? Smoking weed is a possibility, but not exactly a human right, at least not as much as the right to live, to physical well being, etc. I'm skeptical of the claim because at the same time anti-smoking bigots are using human rights and public health as an excuse to restrict smoking and some are planning on banning it. So why does it go both ways? Well what would you say about someone who consents into slavery? Isn't that behaviour so self-destructive (and by definition means the death of your personhood) that we should put an active stop to it by making it illegal to be a slave?
Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
