How does marijuana affect the brain?

    How do you feel when you drink? Huh? I don’ t remember. I have to ask others if I danced on the table, beat my kids, slapped my wife. Weed, laughter, tv, jokes. If government would smoke one it would already be legal.

    First off, it comes from the flowers, or "buds" of the cannabis plant, not the leaves. Secondly, marijuana is NOT a stimulant πŸ˜‚ that’s putting it in the same category as cocaine, caffeine, and Adderall



  11. Batzhor on January 11, 2020 at 8:34 am

    Weed a stimulant ? Get your ass out of here, it’s either a downer or a trip into the thought abyss πŸ˜‚πŸ˜‚βœŒοΈ

    Weed makes you stupid and mentally ill



  26. The Streak on January 11, 2020 at 8:43 am

    Something else could be the way pot makes your tiny blood vessels dilate. Your eyes get red because of increased blood supply, but what other capillaries also expand? My blood pressure drops about ten minutes after smoking pot. My eyes get red, too. Would increased blood flow in the tiny vessels of the brain make my brain 1/2 degree warmer? It feels like it.

    Would a small cut in my skin heal quicker with a drug that could expand the blood flow in the tiny vessels? Might pot speed up healing for a minor eye injury? Could an increase in the blood flow of tiny vessels in the lungs explain why we don’t see the lung damage with pot smoking that we see with tobacco? Tobacco constricts tiny blood vessels.. it does the opposite.

    Such research is illegal

    Not to criticize you but there are two differences I’m going to tell you what the differences are imma make it short. I smoke marijuana everyday and I haven’t forgot to smoke marijuana I haven’t forgot to eat or drink a beverage take care of my children none of the above have I ever forgotten to do moving slow is not part of the side effects of marijuana but everything especially eating memory Focus heightened



  28. lauren bell on January 11, 2020 at 8:44 am

    I feel like people smoke & automatically think they can’t do shit . It’s mental thing . How would I forget something I’ve known how to do for years . People choose not to remember



  29. rindel donnet on January 11, 2020 at 8:47 am

    I am high, watched the beginning of the video, tried to remember the numbers, couple minutes later I realized you wouldn’t be testing us(the viewer) so I gave up. Made a phone call, sent some texts.. came back to youtube forgot the video was paused and I resumed. Then about 4:10 You were about to show how these people have bad memory, Then I shout, "875425." Much longer than 30 seconds later, highernuhmuh, nailed it(no cheating). Yet, I still agree with you. Though, my memory is better when I am hydrated and ate a lot of sugar. Also, I haven’t had a vaccination in 10 years. I am literally a god compared to my older self. I do eat a lot healtheir and am less stressed since dissolving my ego. Many factors, I am high, smoked 10 years straight. I am ready to quit, problem is I wake up grab my pipe, smoke before I remember to quit.

    Take it from a stoner, weed is bad



  31. bornofthefire thegiftofgod on January 11, 2020 at 8:52 am

    On a powers and principalities level A super storm will strike my enemies they will be literally be seen falling from the skies and heavens on a unprecedented level when they do reality will be blended for this ignorant people on this planet playing with fate



  32. gi gi on January 11, 2020 at 8:52 am

    My cheek on the right side keeps getting numb. It’s been 3 days since my first time smoking weed. I experienced this the first time i smoked weed and i thought it will go away after I get high but it didnt. Can someone pls explain to me what happened to me? I think the effect of the weed became permanent to me



  33. FusterCluck on January 11, 2020 at 8:54 am

    Now do the same with Alcohol and compare the two results, then tell me which one is worse. I don’t need to wait for the results actually….we all know alcohol is far worse, kills 2 million people a year, yet its completely legal and cannabis is far less dangerous for yourself and others, has NEVER killed anyone, yet remains illegal in most places. Go figure.



  34. Agam Soni on January 11, 2020 at 8:54 am

    Its the most important plant of ayurveda which was used in india science 50000 years …
    Ayurved explains every explanation for this to use it as a medicine



  35. Alex Rodriguez on January 11, 2020 at 8:55 am

    So would you say Anandamide regulates the feelings or modes of being within our brain and THC free’s this process or heightens it?



  36. bornofthefire thegiftofgod on January 11, 2020 at 8:58 am

    I will create a judgement using the horrors of bad trips I experience my son and thousands of others around the world. I will pour out this bad trip judgment on the gov individuals groups persons my enemies who are targeting my son.



  37. FriedEgg on January 11, 2020 at 8:59 am

    I’ve been using weed almost daily for over 20 years and I definitely worsens your short-term memory. It’s still possible to remember stuff though. I currently hold 4 originally random 16 character passwords in my head, plus about five 4-digit pin numbers. I liken learning and remembering things while stoned to running in sand.



  38. KubaBooba on January 11, 2020 at 8:59 am

    I love the brain! It’s so fucking cool!



  39. Darlung James on January 11, 2020 at 9:00 am

  42. bornofthefire thegiftofgod on January 11, 2020 at 9:03 am

    When this judgement is poured out the skies around the world will become ominous



  43. Sexual Tyrannosaurs on January 11, 2020 at 9:04 am

    I remember growing up we could remember everybodies phone number by heart but now with these smart phone most people dont even remember their own number…I would say that smart phones have a more detrimental effect on the brain than cannabis by far…plus we can eat cannabis nobody is making you smoke….



  44. colin shore on January 11, 2020 at 9:07 am

    This only one side of the headphone at a time audio hurts my brain

  48. Chad Finzel on January 11, 2020 at 9:10 am

    Yes it amplifies your mood or personality. If you’re a happy person it makes you happier. If you’re a stupid person it makes you stupider.



  49. Humboldt Harry on January 11, 2020 at 9:12 am

    This audio molested my ear drums. It was not a pleasant feeling.
