Make sure to have a half to a full tablespoon of locally-harvested honey in the morning and at night - as it can help you adapt to the pollens in the air from any plants you might have as well as the buds themselves. In this case, might also be good to only buy your stuff from local farms. Also, there's a brand of homeopathic allergy medication called BioAllers that many people who smoke swear by as being highly helpful.
