🚨 Massive 44-year study reveals that long-term cannabis use does not accelerate cognitive decline.
It debunks long-held myths about the drug’s impact on brain aging.
For decades, concerns over the long-term cognitive effects of cannabis have fueled public health warnings, yet a comprehensive 44-year study from Denmark is now challenging those assumptions. Researchers tracked more than 5,000 men from early adulthood into their mid-sixties, comparing intelligence scores recorded at age 20 to follow-up assessments at age 64. The results, published in the journal Brain and Behavior, found no evidence that cannabis use accelerates cognitive decline. In a surprising twist, those with a history of use actually showed a marginally smaller decrease in IQ points—approximately 1.3 points less—than their non-using counterparts, effectively questioning the notion that the drug inevitably impairs long-term mental acuity.
While the findings are striking, experts note that lifestyle factors and 'cognitive reserve' may play a significant role in these outcomes. The study revealed that cannabis users in this cohort often possessed higher baseline IQs and education levels, which are known to influence cognitive resilience. Crucially, the researchers discovered that neither the frequency of use nor the age at which an individual started using the substance significantly impacted their intelligence later in life. Although the study was limited to men and relied on self-reported data, it provides some of the most robust longitudinal evidence to date that past cannabis use does not inherently doom the aging brain to a faster decline.

Crypto trading activity is declining:
Daily trading volume across the 44 spot crypto exchanges tracked by Kaiko fell to ~$15 billion last week, the lowest level of the year.
This marks a -70% decline from January peak levels.
By comparison, in February, there were 2 trading days when volume exceeded $100 billion.
As a result, the average daily volume trend has fallen -50% since December 2025, to $20 billion, the lowest this year.
Meanwhile, trading volume remains heavily concentrated, with the 6 largest exchanges accounting for more than 60% of total activity.
Crypto market liquidity is drying up.
A documentary gave a homeless man $100,000 with no strings attached. Six months later, it was all gone.
In 2005, filmmakers handed Californian Ted $100,000, free financial advice, and a camera crew to record what happened.
At first, his life improved. He moved into a motel, then an apartment, and finally had stability.
But as the money disappeared, he rejected expert advice, trusted only his instincts, and eventually returned to living under the bridge.
The experiment showed that money can create opportunity, but without the habits to manage it, opportunity can disappear just as quickly.

🔥CHARLES HOSKINSON: “I’m so tired of talking about Ethereum.”
The Cardano founder angrily shut down a reporter from The Block who asked about Ethereum’s founding.
“You’re lazy. Do some basic f***ing research.”
"It's been 12 years and I've answered the question 400 times in every g****** interview.”
“If a traumatic event happens in your life and you’re done talking about it, it’s not appropriate to keep badgering someone about the g****** thing after 12 years.”

It’s official:
Apple, $AAPL, is now the second company in history to surpass $5 trillion in market cap.
This makes Apple the largest company in the world, now 6% larger than Nvidia.
If you invested $10,000 in Apple in 2003, you would have $15.5 million today.
Truly historic.
