Why is love potion legal?

I'm curious, why exactly is the concept of a love potion considered legal in some cultures and contexts? It seems like such a powerful tool that could potentially manipulate people's emotions and decisions, so shouldn't there be stricter regulations or even outright bans on its use? Are there any ethical considerations or potential consequences that are being overlooked here? And if love potions are indeed legal, what safeguards are in place to ensure that they're not being misused or abused?
