I had a reaction like that the first time I had crab meat. For a long time I was afraid to eat it again, but when I finally did there was no problem. I'm not a big fan of seafood anyway, but every time since it's been no problem.
I would suggest that you get some just regular old weed. Not dab, not vaporized, just regular old flowers that come off the plant, which today are called 'nugget' or 'nug'. Just try a little, of course, and see if it gives you any problems. If so, then you know it's the weed you're allergic to, not some chemical added in processing.
