Helps relieve anxiety and eases social contact. For me personally its just a mood enhancer and makes listening to music so good. About 500-1500mg is a normal dose, lasts for up to 24h and should not be taken more often than once a week.
Obviously not all of them, just like not every single person would abuse superpowers. But the numbers are still orders of magnitude higher than everywhere without weapons, even though shooting someone still has consequences unlike doing shit while invisible.
