What you need to know is that it will make you dumb and stupid, and you'll sit there giggling to yourself incapable of any coherent thought, like a drooling idiot. At least that's what it'll look like from the outside. From the inside, you'll feel like you've opened a door to a magical land of true understanding, like the veneer of convention has peeled off the world and you can finally see the underlying superstruture of reality. So not only do you turn into a drooling idiot, you turn into a delusional drooling idiot.

And then it takes over your life because it takes days to really get down from those dizzying heights of sudden chemical revelation, only you don't realise you're still high so you still think you really made all those lofty realisations. Then you go and have some more because you 're still incapable of rational thought and who's going to stop you anyway? It can be years before something breaks you out of this vivious cycle of making yourself stupid and being too stupid to understand how stupid you have become as a consequence.

So don't do it. Life's too short. Go read a book. Go learn a craft. Go get a hobby. Learn woodcutting. Learn to bake. Learn to cook. Have more sex. Maybe get a degree or two. But don't do shit that burns your brain because you only get one brain. And it is very easy to damage irreparably.
