Currently, many states in the U.S. allow residents to possess medical marijuana. The age requirement for medical marijuana is 18 years in these states, so adults with qualifying medical conditions can use the limited number of ounces allowed in each state for medical use. However, the regulations for obtaining a medical marijuana card or a “weed card” differ from state to state.
In 2021, there are thirty-six states that have passed medical marijuana laws. That makes it legal for patients who have a qualifying health condition to use medical cannabis legally. The age requirement for medical marijuana is eighteen (18) years. And anyone under the age of 18 is required by law to have legal permission from a parent or guardian.
If you are eighteen or older, you may be thinking about getting your medical card. Many states provide telemedicine health evaluations. That is the first step to getting your medical marijuana card. And if a doctor approves you, you can register as a patient in your state medical marijuana program.
In states where recreational weed (or adult-use) has been legalized, you have to be twenty-one or older. You can’t buy cannabis from a dispensary if you are under the age of 21. But many people don’t know that you can get your medical card before you turn twenty-one if you have a qualifying health condition and without parental consent.
Why Do You Have to Wait for The Age of Eighteen to Get a Medical Card?
While cannabis is acknowledged as a safe alternative medicine for adults, some clinical studies raise concerns regarding minors. Researchers have 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. That is to ensure that medical marijuana is the last therapeutic resort when other treatments have not worked for a child with chronic health conditions.
Cannabis and Puberty: Tweens and Teens at Higher Risk of Cognitive and Mood Disorders
Teens that use cannabis are also at risk for developmental problems. That is because the neurological system (brain) continues to develop until about twenty years. And early use of cannabis can contribute to a higher risk of developing the following mental health disorders:
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. And some studies suggest that early tweens and teens are more at risk when they consume cannabis whileundergoing puberty.
