Do you think that it should be legal, or illegal, for people to sell drugs to teenagers? Genuine question.
Which almost makes me reconsider my entire political standpoint. So thanks! I can't answer your question, but I assure you, you have me thinking.
With that said, we as a society do have a responsibility to protect children - free access to heroin (for instance) would be incredibly harmful to children, who have not formed the ability to properly assess risk. Allowing for unfettered access to heroin for adults is much more complicated. Given how easy it is for most adults in America to access the drug, I would argue we are already contending with many of the complicated factors of unrestricted access already. How to deal with those problems is something I don't have many good answers for.
Of course, yeah, I meant it more in the "no rational actor would choose to use heroin" sense :)
