Many marijuana consumers get medical cards because they provide extra protection to patients and marijuana businesses. Marijuana is still illegal on the federal level even though many states provide medical and recreational cannabis, so a medical card affords legal protection for patients under the state’s marijuana laws. A medical marijuana card can also help consumers save money depending on the state, because some have established tax benefits for those with medical cards. Medical patients purchase marijuana for a cheaper price than recreational users, so there are many positives to getting medical marijuana cards. The process to actually get a medical marijuana card isn’t always simple though, so many consumers and patients don’t bother getting cards.
