Because he is not his usual self when under the influence.
He he does not have all his faculties and this means he is not his alert and usual self and some people haven't a clue at all.....when stoned! Well shove him to bed, or in a taxi home, and don't get too entangled for it can be not a very good experience. Try to influence him not to get stoned, its the pits.
Why are you with someone who does drugs? It limits the abilty to get good jobs, makes you stupid and broke cause you're blowing money for your next high and makes your kids born with medical issues. Don't bother replying with" he's not a dope head, he just does it once in a great while" cause thats a crack head response. Find someone who doesn't get high and stop using yourself (if you do).
Because when he is stoned he is well away with the fairies in Fairyland.
