What about the FDA‘s bans on food ingredients?
They don’t work, companies just become more secretive?
As I said in the sibling comment, I’m talking about people’s own will. You can’t say “Ban smoking” and expect that all smokers quit.
You can’t ban something without severe consequences for the producers and just hope the consumer will follow the ban.
The problem with your example, is that any government body can randomly test the products from a company, and test for compliance. The government can also measure the CFCs in the atmosphere and look for a decrease year over year.
Right now, the Aus government isn't fining the companies, hopefully they will.
As for social media, people don’t really want to stop or avoid using it
You are right in the sense that less and less people smoke. You just can’t exclude that we are people and do stupid things to look cooler or something
