i dunno man, if you become unco when stoned i believe youre just not trying. it takes longer but i love shaving while stoned, each stroke of the razor is so thoughtful though i hate shaving anyway, so now i am growing beardness
i guess it depends on each individual's facial hair growth. some people complain of itchiness, but i dont have a problem with that. and my girlfriend loves the hair, so it doesnt prevent my chances of getting in bed with a woman, which i believe is a very common protest. the only problem ive found is that some jobs dont like applicants with facial hair because they can seem ungroomed. at any rate, humans have beards for some reason, i dont think this reason is 'to be shaved' yes i like endorsing facial hair.
