Seriously, if you want even more restrictions on what your fellow human beings are allowed to do and enjoy, you should be very happy in North Korea and I can only invite you to prepare your visa application papers. Wait, US citizen are not allowed in NK. Hope you are not US citizen?
Cigarettes are something that have nothing but negative consequences - for the smoker, for those in the vicinity of the smoker, and for the impact on the health system supporting the smoker.
It defies reason that these small poison sticks are still sold, especially to younger people who have not yet developed the crippling addiction held by those who have been smoking for years. It's really quite sad that people still seem to be stupid enough to volunteer for this long-form suicide.
Farting, on the other hand - is great. And, the release of hot air that's mildly annoying to others, faintly humorous, and quickly forgotten seems to be something that you certainly would relate to.
If they had nothing but negative consequences, no one would smoke them. Obviously the people who do smoke them are getting some kind of value from them.
