After 3 months, data was available for 2,112 patients and then 777 after a year. Around 25% of the population acknowledged that they had suicidal ideations at the start of the study; they also suffered from depression, and experienced other symptoms including difficulty sleeping, poor health, and low quality of life. That said, the researchers noticed improvements after three months of treating them with medical marijuana. Rates of suicidal ideation dropped to 17.6% and they saw improvements in depression scores as well. Because of this, the researchers concluded that medical marijuana could be a valuable tool in the treatment of depression and suicidal ideation, which are extremely difficult to treat.
