Recent results that have been published in Frontiers in Pharmacology indicate that marijuana improves cognitive performance, especially those governed by the frontal cortex.

Beta Minds reports researchers from McLean Hospital, Harvard Medical School, and Tufts University have begun preliminary investigations that have found incredible benefits from the plant’s use, including the improvement to “our ability to utilize the knowledge acquired by mental processes in our brains.”

24 patients were studied over three-months.  They were regularly measured with cognitive testing, including the Stroop Color Word Test and the Trail Making Test.


Researchers found that patients did increasingly well on the tests.

A McLean Hospital report reads:

After three months of medical marijuana treatment, patients actually performed better, in terms of their ability to perform certain cognitive tasks, specifically those mediated by the frontal cortex,” explained Staci Gruber, PhD, director of the Marijuana Investigations for Neuroscientific Discovery (MIND) program at McLean Hospital.

Study participants also reported improvements in their specific clinical conditions, sleep, and overall health as well as a decreased use of conventional medications, particularly opiates.

We saw a 42 percent reduction in opioid use,” reported Gruber. “This is significant, particularly for those of us in Massachusetts and other areas of the country where the opioid epidemic is ravaging so many. This preliminary finding certainly warrants deeper and broader investigation.

“As a clinical researcher, I’m not interested in exploring only the good or the bad, I’m only interested in the truth,” explained Gruber. “That’s what our patients and our recreational users have a right to know and a right to expect from us. People are going to use it. It’s up to us to figure out the very best and safest ways in which they can do that.”

We need more studies that actually look for the truth, as Gruber states he is doing. Once people know the truth, rather than what people want us to believe, then everyone can determine for themselves if it is right for them. With so much misinformation out there, partially due to the irrational prohibition of the herb, it is hard to know what to believe.
