    I’ve tried emailing you and messaging you all on social media.

    Your explanation is absolutely wrong.

    Cannabinoids are the retroactive signaling molecules of the human body. They prevent excess neurotransmitters from firing, they do not interrupt a refractory period. They cause it.

    Please change this in the about or make a new video.

    This is incredibly irresponsible and I will have this called out in a professional publication if you don’t actively correct it.

    You’re sharing inaccurate science. This another example of how disinformation is spreading too easily online. The people attempting to be topical authorities on science are not even fact checking their content or checking their emails.

    ADVICE FOR THE POTSMOKER: Teens who smoke pot at risk for later SCHIZOPHRENIA, psychosis (via Harvard review). Also, I watched an Amazon documentary of a MENTAL INSTITUTION in France, they said their SCHIZOPHRENIA patients may happen from marijuana use. They all look like walking zombies that got a lobotomy NO JOKE. https://www.health.harvard.edu/blog/teens-who-smoke-pot-at-risk-for-later-schizophrenia-psychosis-201103071676

  30. Loki Beckons on October 19, 2020 at 8:27 pm

    I just realised that the way neurons interact by letting neurotransmitters move to the dendrite of the next neuron and exciting or inhibiting it… is the same way that transistors in a cpu work, by keeping the gate open or closed. wowzers, we really are just a big ol biological binary system
