Nowadays, there are many products that unhealthy effects on people as proven by scientists. That's a reason for some people's requirement to avoid selling such products and drinks. I can't say that I have the unambiguous solution for this extension, but I am convinced that every stick has two ends. First and foremost, we have many examples from the world history of such bans. For instance, the dry law in the US in the 30th years of the 20th century, or the same law in the USSR in the 80th. The result of such laws were appearance of illegal alcoholic drinks, sometimes they were poisoned, and people died or became handicapped after they had drunk them. It's always the question of supply and demand. Moreover, from these examples, we can study that direct avoidance can have the opposite effect on people.
