I think I know the problem here: If you are smokling (inhaling) cannabis OIL then stop. It is making you sick to your stomach. The oil from vaping should be held in your mouth and NOT inhaled (like a cigar) because the oil is better absorbed through the mouth membrane than the lungs.
But even then, depending on the oil/vape, this may be causing you to not want to eat. Try doing smoke only, or edibles.
