No. You only need a government-issued photo identification card showing that you are 21 years old or over. If you have a state-issued Medical Marijuana Identification Card (MMIC) from the California Department of Health Services, you will also need a government-issued photo identification card showing that you are 18 years old or over. By providing your MMIC information, your sales tax will be waived (state-required excise tax will still apply). You can find more information about obtaining an MMIC on the CDPH website.
