Teens who use marijuana may be at greater risk of permanent brain damage later in life, a study has revealed.
About 18 million Americans report using marijuana daily or nearly every day, and use is on the rise, largely due to recent decriminalisation across the US. From 1992 to 2022, for example, daily and near-daily use saw a 15-fold increase.
About one in seven of those users are teenagers, whose brains are still undergoing rapid changes in areas responsible for judgement, decision-making and memory.
Now, the largest-ever study of American teenagers has found regular cannabis use restricted vital growth in memory, attention, language and processing speeds over time, despite normal development when they were younger.
However, as they moved into later adolescence, their development in these areas slowed compared with their peers.
Experts from the University of California San Diego believe the culprit is tetrahydrocannabinol (THC), the psychoactive ingredient in marijuana, which was linked to worse memory in teens compared with cannabidiol (CBD), which is not intoxicating.
It is thought THC may lead to shrinkage of the hippocampus – the brain’s memory centre – and changes in white matter, which controls how different parts of the brain communicate with each other.
The researchers said while the deficits were small, the brain develops so quickly during adolescence that even subtle shifts could affect school performance and daily life.

Yes, he did stop maturing. Unbelievable as it seems, he enrolled in a PHD program in education. He doesn’t even look up words he doesn’t know; and, I think his vocabulary is shrinking.
A lot of those guys came home using pot, and some nastier stuff as well. That war took a mental toll, like they all do.
Instead, it should tell you something.

The book on Marijuana has yet to be written.
“Just ask Jordan Peterson.”
I just read up how he is doing. He has a huge place in Arizona. He is quite ill and has not been out much for a year. I remember that prior, he was on a 100% carnivore diet an feeling great. His daughter has been all carnivore for a few years and doing well. It cured her health problems.
Yes, absolutely.
I think that parents and teachers cannot be too mindful of this danger and warn their children/ students accordingly, i.e. by showing them shocking (but realistic) films of patients whose minds have been wrecked by drugs.
Or even having them visit a drug rehabilitation center…
Especially on the modern „brands“ of cannabis plants, which contain several times more THC than older breeds in the Sixties used to.
Weed or booze.
The never ending argument.
Jack Nicholson just turned 89.
The story goes he was friends with Larry Hagman who liked to consume a bottle of champagne every day before noon and that was just to start the day.
Nicholson conerned for his friend’s health told him that stuff will kill you the way you are going.
Lighten up, smoke some weed.
I think Hagman had the money to have a liver transplant which most alcoholics don’t have but he’s taking a dirt nap and Jack is still around telling stories.
