i would guess about 99% of us on here kill the male at first confimation that it is in fact male,.. we do not do anything with it ,.. we do not grow it out to finish,.. it will ruin the rest of your females if you leave it in there,..
(like i said almost all of us kill them at first sign of male,.. but you can use them to make seeds for another crop ,.. and breed strains and a few other things)
but to answer if you can smoke it or not ,..well you can,.. but its going to be very low if any thc and that will not do anything for ya,... for sure zero buds will form to smoke, only leaf... so i would just kill it ,...IMO
