In my country, the trend of smoking tobacco in tech circles is going down. I am not sure why but it was considered quite "cool" if you code and smoke. There was a trend of smoking cigarettes after every hour to have that much-needed break to think about the problems that you were stuck on and bitch about HR. However, I am seeing a decline probably due to vaping.
I hate tobacco with a passion. It's irritating to be around. However banning tobacco seems authoritarian and pointless. It will be like prohibition all over again.
Great... another drug war that will not work.
Instead of prohibiting sale of tobacco (and drugs and alcohol), insurers should refuse to insure anyone taking them in large quantities.
