If someone invented a love potion, how much do you think that would be worth? Would it be legal?

It would be illegal i think
If someone used it and forgot or didn't dose them again in time when it wore off they'll sue the person and rhe company that made it for being trapped in the spell don't think they'll make much money

The cautionary tale of Tom Riddle Sr would halt all love potions. It's basically a long term date rape drug.

So much for leaving huh?

Definitely not legal
It’s priceless to the ones who would use it

Depends on what the love potion actually does.
Just make you very attractive or control your mind?
Either way very expensive
