well if you vaporize it and get an allergic reaction then no. if your allergic to cannabis, theres no method of ingesting it thats going to change that
if you're allergic to the oils in marijuana then you are literally fucked.. there would be no way for you to get high comfortably... since THC is the oil basically.. with a handful of other non-psychoactive compounds.. therefor you CANNOT get high from marijuana without allergic side effect.. i'd say your next best bet is opiates
If you are allergic then you are allergic. Period. You can take medications in order to block your histimine responce, IE and allergic reaction but other than that you would need to go see an allergy doctor. They can give you allergey shots that will help you with generic weed allergies but not specific to Marijuana. It can take up to two years of shots to make that go away. Feel free to discuss it with your doctor. My suggestion. Otherwise take a pill and suck it up.
Lol allergies wouldnt be able to stop me from smoking, then again i dont know the symtoms you experience. If its something generic i would suggest just getting some mild medication (like nasal spray or something off the shelf) and use that after you smoke to alleviate you symtoms
