Mental Health Issues

Older people who use marijuana are more likely to be stressed or depressed than non-users, according to a review of studies published in the journal Gerontology and Geriatric Medicine. This could be because some marijuana users are self-medicating with the drug instead of seeking professional help. But because cannabis directly affects the brain, it can complicate mental health conditions or interfere with treatment. "Marijuana should be used with caution if you have a mental health condition," says the Mayo Clinic

Could marijuana increase your risk of senility? Researchers have found an association between the use of THC (the active ingredient in marijuana) and thinking and perception disorders in people over 50. "Self-reported thinking or perception disorders reflect alterations in thinking and perception typically described under psychotic symptoms," the authors wrote.

A 2017 study found that marijuana users 50 to 64 years old were more likely to participate in risky activities, including driving under the influence, theft, and physical violence compared to older nonusers. Other studies have found that marijuana users 65 years or older were more likely to drive under the influence compared to older adults who don't use pot. And a 2018 study found that marijuana use has been associated with injury in older adults, along with visits to the emergency room.

Drug Interactions

According to the Mayo Clinic, marjiuana can cause side effects when mixed with other medications. These include increasing the risk of bleeding, lowering blood pressure, reducing the effects of antivirals, increasing sedative effects of certain drugs, and affecting blood sugar levels. That may make marijuana use riskier for people taking anticoagulants or medications for chronic conditions like blood pressure, HIV and diabetes.

Poor Diet

Marijuana is known to increase appetite. This can have negative health effects for older adults, especially if you're at an unhealthy weight or have diabetes or heart disease. Several studies have found that found marijuana users self-reported a higher intake of alcohol, sodium, pork, cheese, and salty snacks, but fewer fruits and vegetables than nonusers. "The stimulation of appetite … could be life-threatening for someone with diseases such as diabetes and cardiovascular disease, where a healthy diet may be vital to improved health outcomes," wrote the authors of a 2018 review of studies on marijuana published in Gerontology and Geriatric Medicine.
