We try to do our best to organize the Medical Marijuana Doctor's schedule each day. The $20 is just a deposit to hold your appointment time and date. The $20 is completely credited to the total exam price, so you will never lose it. You will be required to pay the leftover balance at your appointment time. If for whatever reason, you are not approved for Medical Marijuana, you will be given 100% money back including $20 deposit. The only way you will lose your deposit is if you no show without rescheduling a new appointment. You are allowed one to reschedule. Most of our competition requires full payment upfront, so we try to do everything we can to make this process easy on our patients.
