Possible to be allergic to the cannabis plant (contact or inhaling allergens while cultivating) but have no allergic reation to ingesting the bud?

THC: Marijuana smoke contains bronchial irritants. Inhalation with marijuana is more prolonged & deeper than with tobacco. Higher combustion temperatures are reached because it is smoked to a shorter butt. This leads to a carboxyhemoglobin concentration that is 5 times higher than tobacco. 3 times more tar is inhaled. Prolonged use of cannabis can lead to airway inflammation& wheezing & cough.
