All you need to grow, posess, and go to clubs in CA is a hard copy perscription. The card is just an ID. In fact having the ID lets the county (cops!!!) know who you are, that you have it, and where you live. If you just get the perscription no one except you and your doctor has to know. If a cop tries to cite you a perscription will do, and if it doesnt a judge will have to let you go on it. DONT GET THE PIECE OF PLASTIC ITS A SHAM!!!
