Medical cannabis research shows improvements in anxiety and pain management

Multiple studies published in 2026 have examined the effects of cannabis and cannabinoids on anxiety and related conditions. Research includes human observational studies, randomized clinical trials, and laboratory experiments involving CBD and THC.

A large-scale study conducted by the Minnesota Office of Cannabis Management involving over 6,600 patients found that medical cannabis use among cancer patients led to improvements in pain, nausea, vomiting, anxiety, and depression, while also enhancing sleep quality. Among cancer patients reporting moderate to severe pain, 30% experienced a reduction in pain scores of at least 30% within four months.

Other research highlights include a UK-based study of 698 patients from the Medical Cannabis Registry, which linked cannabis-based medicinal products to sustained improvements in anxiety, depression, and sleep over a two-year period. Additionally, a randomized controlled trial involving recreational runners found that 300 milligrams of CBD increased feelings of calmness and relaxation while reducing perceived exertion during exercise.
