In a study released by the State of Ohio Board of Pharmacy, findings revealed that more than two-thirds of the state’s medical marijuana cardholders are over the age of 40.

The data showed about 21% are between the ages of 40 and 49, another 21% are between 50 and 59 and roughly 20% are between 60 and 69. Shockingly, only around 10% of cardholders are between the ages of 18 and 29.

Chronic pain is most commonly cited as the reason for the use of medical marijuana, as many residents across the Buckeye State have reported to their physicians that they use medical marijuana to cope with injuries sustained after doing years of manual labor.

Findings also showed that older users have more disposable income, and are less likely to be drug tested.
