Do the 4 $50 coupons for new medical patients have an expiration date from time of issue?

Our vouchers are valid throughout the time your medical card is valid (there's no expiration date necessarily)

You get the 4 vouchers if you are a new/renewing patient. You must sign up within 30 days of getting your certification. They are good for a year, and then when you recertify you will get 4 more next year

I am not sure. I believe you have to use the first one within 30 days but am not positive.
