You might be developing a weed allergy.
Take some bud or leaves and rub it on your arm, document what happens.
Yeah man I literally smelled some gas last night , some amazing smelling bud, and that sent me south, runny stuffy nose, sneezing, the whole nine yards. And it got a tiny bit worse when I smoked too lol.
I break out in hives when I mess with my plants and get shit on my skin
