I just read that if BHO wax isn't 'winterized', it can have cannabis 'cuticle' (waxy outer layer?) that doesn't get burned off at vaporization temperatures and can accumulate in the lungs. if I'm in a legal state, does that give me any reassurance that wax I buy at a dispensary will have been winterized? if not, do you think 'cuticle' residue in the lungs is a serious enough concern that I should only do wax via high-temperature dabbing (i.e. a nail)? thanks for any useful info!
