New Study: Cannabis May Grow Stem Cells, Repair The Brain After Injury

A new study being published in next month’s issue of the journal Biochemical Society Transactions, and published online early by the National Institute of Health, has found that the brain’s endocannabinoid system – which is activated through cannabis use – has neuroprotective and immunomodulatory capabilities, and may lead to the growth of stem cells.

“Activation of cannabinoid receptors suppresses chronic inflammatory responses through the attenuation of pro-inflammatory mediators”, states the study’s abstract. “Moreover, the endocannabinoid system directs cell fate specification of NSCs (neural stem cells) in the CNS (central nervous sytem)”.

According to researchers; “Pharmacological blockade of CB1 and/or CB2 cannabinoid receptors abolish or decrease NSC proliferation, indicating a critical role for both CB1 and CB2 receptors in the proliferation of NSC via IL-1 signalling pathways.”

They conclude; “Thus the endocannabinoid system, which has neuroprotective and immunomodulatory actions mediated by IL-1 signalling cascades in the brain, could assist the process of proliferation and differentiation of embryonic or adult NSCs, and this may be of therapeutic interest in the emerging field of brain repair.”

  1. Really not sure what the thc levels was I smoked a lot in the 70s and long term memory was above average but did notice my short term was not that great but I did also suffer a few injury in sports so that may of been apart of it

  2. Juice is awesome if you have access to fresh raw leaves in your area. If not some flowers fine ground into a breakfast shake works wonders too as long as dosage is light enough to not affect the blood pressure. AZ is now offering infused tonics and tinctures. Thats the beauty of this plant is its diversity to help the body however you choose to use it. And i knew a guy who was in a longterm coma and now he lives better with cannabis than without it. Good luck to you and yours

  3. I have smoked pot for 20 years there is nothing wrong with my short term memmory. I get stoed on a friday night while my mates get drunk. I remember everything, they remember very little.

  4. Sounds like a scare tactic. And I think cannabis would help her brain to heal. Don’t have to smoke it, though.

    It’s kinda hard for me to accept, with all the chemicals and toxins in our air, land and water, that cannabis smoke is somehow worse than that…

  5. My daughter was in a coma for 10 mths they told her if she was to smoke she could have seizures or a stoke from lack of oxygen to her brain she use to smoke b4 her mva

  6. I have read two different theories on when the endocannabinoid system develops, one is that it develops before we are born, and the other is that it develops months afterwards. I wonder if aspirin works the same way as acetaminophen.

  7. I’m sorry? Where was the proof of “neuromodulatory consequences during development” due to the endocannabinoid system? Though I do find it interesting that they’re saying that the endocannabinoid system activation is what makes acetaminophen work while also still not declaring cannabis a safe and effective medicine.

  8. As I read the article, I wondered what else activates the endocannabinoid system. Here’s something interesting:

    A 2010 study done in North Chicago, by what looks like a doctor associated with the military…

    Acetaminophen use in children has been associated with increased autism risk. Recent evidence suggests that acetaminophen’s analgesic actions result from activation of the endocannabinoid system, and activation of this system can have neuromodulatory consequences during development. This investigation was performed to determine if there is evidence to support the hypothesis that acetaminophen use can trigger autism by activation of the endocannabinoid system.
