Just because you don't know anyone that does doesn't mean this exists. I've heard from people that things being illegal adds some type of utility/satisfaction to it. I had this discussion about a month or two ago and some people, for instance, experience this about alcohol after a bit after being 21, as there are no worries about being caught in the act, etc.
And in no way am I saying I think that way, I consume alcohol and marijuana illegally and the fact that they are illegal for me does not add any satisfaction for me
