the dr i see in vegas for my recommendation also believes everyone would benefit from using cannabis but unfortunately is saddled with a need for medical records. it doesn't much matter what the chronic (no pun intended) problem is but the records of having a long lasting condition is the key...whether it be arthritis, sleep apnea, general pain and even asthma (it's on the list here) it needs documentation or a thorough physical before he's allowed to sign the forms. so for those seeking a card, get busy with the paperwork!
