I understand the difference in effects and I'd say this - whatever it is - is less offensive than love potions.
The love potions are by definition given to people who don't love you to make them love you. Never mind that it's not real love, but you're still making someone 'fall in love' with you. I think kissing random people is a lot less intrusive than fucking with people's emotions.
Besides until and unless they are violating existing laws, there are no consequences.
