The hard copy of the recommendation is an official legal document that allows you to use Marijuana legally. After obtaining the recommendation you should bring it to a dispensary or cannabis club for your first visit. After the first visit the MMJ-ID Card is typically all that’s needed. The MMJ-ID Card is a convenient way to identify you as having the legal right to use and possess Medical Marijuana. The MMJ-ID Card can provide you with peace of mind, as it provides documentation you may need in certain situations, such as traffic stops.
