stay away from it
its a lot of fun, but it directly changes the way your brain cells send signals
it allows you to feel sensations that are impossible; colors, smells, tastes, sounds, touch, seeing things in new ways you couldn't comprehend before, extremely high pattern recognition, make you hear words no one has spoken
but it can make you develop irreversible mental disorders or go into psychosis
it left me with a panic disorder that shows no signs of getting better a year after i quit
if you really want to experience something incredible, learn how to meditate, lucid dream, or wait for death, because when you die your brain lets off far more signals than could ever be achieved by psychs
