The study involved 50 participants diagnosed with dementia and behavioral symptoms. They were divided into two groups: one was given 1.5 milligrams of medical marijuana pills, while the other received placebo. They took the pills three times a day for three weeks. The researchers also assessed their behavioral symptoms by giving them a dementia questionnaire called Neuropsychiatric Inventory prior to the study and after the three-week study period for comparison.
The test scores showed no significant difference between those who took the medical marijuana pills and the placebo group. However, the study confirmed that the pills are safe to take with minor side effects.
