Currently, an impressive 37 states allow residents to use medical marijuana. This number is up significantly from even just a few years ago, and more and more people are gaining access to cannabis every month.

As wonderful as this is, it can be a little confusing to navigate the rules. Understanding what your qualifying medical condition (epilepsy, multiple sclerosis, Crohn’s disease, etc.) is, figuring out where to get a med card, and finding out what ages are allowed is a learning process. 

The regulations for obtaining a medical marijuana card can vary widely from state to state. To provide clarity, we’ve compiled a list of FAQs related to age requirements in the application process. Follow along as we break down how old you have to be to get a med card in each state.

Already 18? Here’s How to Get a Medical Marijuana Card

The first step to obtaining a medical card is to meet with a cannabis-friendly doctor who will register you as a patient in your state’s medical marijuana program.

Many states offer telemedicine appointments. You can find a doctor in your state here. Remember to bring your driver’s license and proof of residency for identification purposes, as well as any required application fees.

Why Do You Have to Wait Until You’re 18 to Get a Medical Card?

While cannabis is acknowledged as a safe alternative medicine for adults, some clinical studies raise concerns regarding minors. Some research has suggested that cannabis use may have an adverse (or negative) effect on cognitive development during the early adolescent years.

The process for approving minors to use medical cannabis is extremely strict. In some states, it requires the approval of a pediatrician, the primary care provider (PCP), and a parent or legal guardian.

This process ensures that medical marijuana is the last therapeutic resort when other treatments have not worked.

Cannabis and Puberty: Tweens and Teens at Higher Risk of Cognitive and Mood Disorders

Teens who use cannabis are also at risk for developmental problems because the neurological system (brain) continues to develop until they’re about twenty years old. Early use of cannabis can contribute to a higher risk of developing the following mental health disorders:

  • Anxiety
  • Depression
  • Psychotic illnesses and impairments

When parents choose medical cannabis as a caregiver for a child, other alternatives haven’t worked. However, cannabis is not recommended for adolescents under the age of twenty-one to avoid the risk of developing mental health disorders.

Can You Enter a Dispensary at 18?

In states where recreational weed is legal, you have to be 21 or older to enter a dispensary.

However, you can get your medical card before you turn 21 if you have a qualifying health condition and without parental consent. At this point, you can enter a dispensary before 21. 

Can You Use Your Medical Marijuana Card in a Different State?

You can use your medical marijuana card in a different state if your state participates in a reciprocity agreement. Reciprocity agreements allow patients with out-of-state certifications to buy medical marijuana products in states with similar laws.

Note that not all states have reciprocity agreements. Make sure to research the specific regulations of the state you’re visiting before you plan to purchase marijuana there.
