you have been here as you mentioned that cbd can help repair the brain. is that as promising as it sounds? as a scientist, i definitely try to be optimistic. but also cautious. she knows we need more research but getting that done is not easy. it s something we have reported on for years. because cannabis is a controlled substance, getting federal funding is difficult and getting the tulcans by to study is challenging. it took yasmin hurd four years just to get started. i just don t understand why we can t go on to have more in-depth studies the really see indeed if this does work and can be effective for at least a subset of people even if it s not for all the 50,000 people who will die this year. it s hard to do. harvard s stacy gruber has struggled to do this kind of research. her early studies show
and those who smoke after age 16. what we call early versus later onset. gruber s brain scans show the white matter, those are the highways that help the brain communicate from one point to another are impaired in those who start smoking early. maybe that there s underlying white matter connectivity differences. that s your concern, it sounds like, that those highways, those white matter highways are just more disrupted in people who start smoking early. that s what we see. perhaps not surprising given what we know about the young developing brain. that s a very delicate time in brain development, and that s not a good time to be taking any drugs. preliminary research shows that early onset smokers are slower at tasks, have lower iq s later in life, higher risk of strokes, and increased incidents of psychotic disorders. while these studies are not conclusive, some scientists are still concerned because in 2012 35% of high school seniors lit up, and that could mean a gener
tens of thousands from around the country and the world lighting up legally. happy cannabis, y all. for some it s a lifestyle. for others it s a lifeline. we re working with the lupus foundation and rheumatoid arthritis. for all of them, i wonder what was it doing to their brains? some of my patients call me pot doc. your patients call you pot doc? well, they never meet anyone who is as interested as hearing about their marijuana use as i am. dr. stacy gruber is serious about pot. i want you to name the color and not to read it. okay. i met her in her labs in mclean hospital near boston. she s using high-tech imaging to see what happens in the brain when you smoke. when you first smoke, that you light up a spliff, a joint, a smoke, and receptors are throughout the brain respond, and these are areas of the brain responsible for things like pleasure, memory, learning, sensation, sense of time and space, coordination, movement,
april 20th, denver, colorado. we like weed, smoke weed! tens of thousands from around the country and the world lighting up legally. happy cannabis, y all. for some it s a lifestyle. for others it s a lifeline. we re working with the lupus foundation and rheumatoid arthritis. but for all of them, i wonder, what was it doing to their brains? some of my patients call me pot doc. your patients call you pot doc? well, they never meet anyone who is as interested as hearing about their marijuana use as i am. dr. stacy gruber is serious about pot. i want you to name the color and not to read it. okay. i met her in her labs in mclean hospital near boston. she s using high-tech imaging to see what happens in the brain when you smoke. when you first smoke, that you light up a joint, a spliff, a spoke, receptors throughout the brain respond. and these are areas of the brain
the day that i spent with him, he had been smoking all day long. do you feel impaired at all? no, i don t. i feel normal. turns out when you test people who have a lot of experience with cannabis, you don t see many disruptions, but if you test people who have sort of limited history with cannabis, you can see some clear pronounced disruptions. of course, no one thinks that driving when using marijuana is a good idea, but what scientists can t answer is if there is a safe legal limit and if people who use marijuana daily as a medicine should be able to drive. how impaired are they? what is more clear, though, is the effect of marijuana on the young brain. what we see is a very big difference in people who begin to smoke prior to the age of 16 and those who smoke after age 16. what we call early versus later onset. gruber s brain scans show the white matter, those are the highways that help the brain
