I cerainly have an allergic reaction when using certain stains of medical marijuana.. Hives with severe itching.. I was told by one of the dispensory worker's that more expensive strains would cause less of a problem as I was purchasing a strain that was cheaper. Lemon Haze caused a severe reaction.. does anyone else have this problem?? Could other symptoms I'm having be caused by an allergic reaction to marijuana which includes diarrhea and vomiting. No fever.. a little itchy around the nose and mouth.. I have to take a antihistimine every day and I am planning on seeing an Allergist as soon as my stupid HMO referral goes in. I am a Meniere's Disease Patient for ten years. Just wondering... anyone know of a certain strain that might cause less of an allergic reactions.... Itchy and Scratchy in San Diego.
