Ehh, this feels like some kinda survivorship bias / frequency fallacy. I’d argue the people that post and leave comments on social media are already way outside of the norm. It is a power law distribution when it comes to social media participation. Your outliers in this case are very likely outliers in other ways such as in opinions/thinking, risk taking, etc. Drugs really aren’t all that normalized. Sure all my friend circle is full of degenerates, but I am still going to be guarded about my “hobbies” when meeting new people.
