Won't buying meth in Walmart and misusing it be analogous to buying anything in Walmart that can be used to harm oneself or others? You mention alcohol an tobacco but the problem I'm highlighting is: almost anything can be used to harm oneself or others. So shouldn't we be focusing on dealing with those who misuse things rather than keep adding things to a list of things one cant touch without strict supervision?
