"....governments are the ones responsible...."
Which is it? Are you confused? Your latter statement seems to imply that our government should not allow any product to be marketed or used that might cause harm to someone, somehow, sometime, somewhere, under some conditions, if used in excess, if misused, if used illegally, if used in conjunction with something else, if it doesn't please the rule makers, etceteras.
I prefer the concept of individual responsibility.
I don't care if people smoke. I do care that the government wants life both ways - anti smoking but still allows tobacco sales and revenue (taxes). That, to me, is the contradiction and hypocrisy of the issue.I'd rather they get out of the issue altogether. Period.
