Easy money! and technically, dragon tears has no harmful effects, it was just made illegal for over usage (I think)
Nah they said the King personally banned dragon tears, so my theory is that he (or maybe some high-class noble complained) used it so much he got ED and has a grudge against the dragon tears.
Most likely! If anything the way it's described sounds like a relaxer
In fact it's this, high rankings nobles used it so much to have wet dreams the birth rate decreased a bunch and you know that's not good in aristocratic society where you need a successor
Why is he doing black market drug deals? I just don’t understand the train of thought. Still like the story overall though.
