There are two different medical cards now that prop 64 is in effect. To get the taxes off your purchase, it does require the state issued medical card that can only be gotten in person at your local health and human services agency. Any other card from any other doctor or website will just increase your purchase limits.
No card is needed to purchase , this a recreational collective and the tax paid is based on that. I have held a card for over 10 years and have not gotten a different price at any place other then the queen of dragons .. not sure they even do that anymore either.
