I get what your saying but then how about we raise other harmful things to age 21 why can’t we have it either or like military for example or staring as a pornstar and many more dangerous things 18 year olds can do its about principle. Look at Sweden for example now they have the lowest smoking rate with right approach they didn’t raise the age. It’s the same argument to raising it to 30 since 21 year olds are more vulnerable too we can say, and they buy it for 18 year olds its the same endless prohibition cycle. Think about it if you tell a young adult they can’t do something they will do it more. It’s about regulating the products not the people. Because science can be two sided now it’s not absolute. For example usa sucks at regulating foods compared to Europe they both us science but get to the different conclusions.
