How would human culture and civilisation develop if placed onto planet permanently psychoactive planet, e.g. because of low (but inevitable) amount of LSD-like substance in either water or air. To simplify lets assume that the planet is already terraformed and earth-like biosphere reconstructed and that we send there humans without all the tehnology needed to mitigate the effect (i.e. they have to live as is and use no air filters nor antipsychotic drugs). Or just grow them with an autonomous space-probe, assuming they will develop some culture on their own.
