I live in Cali, and I believe that you would be able to get a recommendation through one of the doctors on the CaNorml site. You will need a copy of your medical records and any meds you are taking. You should also look into getting a vaporizer. It eliminates the particulate matter you get from smoking. In addition, you need less for the same high, it doesn't smell hardly at all, you lose that morning cough and you can get high a second time from the "left-overs" from vaping if you use them in cooking. (I am high right now from vape brownies-yum). Since your lungs are already in trouble because of the asthma, vaping should be a necessity for you. You might want to run a search on-- cannabis abstract asthma -- to get more scientific studies to boost your case with the doctor. So get yourself to California and get "legal".
