What do weeds smokers in common with patients with psychosis: study

What a buzz.

Smoking weeds can certainly have an impact on your brain – and not just the potential for some serious paranoia.

Research published last week found that ER visits for use of cannabis over the age of 65 have increased a lot, and older ones who need acute care to get up to 72% more likely to develop dementia.

Now a new study published in Jama Psychiatry has marked another startling change in the brains of Stoners.

The study found that people with cannabis use disorder (Cud) – that is, using weeds to cause problems and damages your life – have changed the activity of dopamine in the brain that resemble patterns observed in psychosis.

Using MRI, researchers found increased dopamine -related signals in the Midbrain regions among heavy cannabis users.

This area is essential for the motivation and processing of rewards and has previously been associated with psychotic symptoms such as hallucinations and fraud.

The more you use – the greater the problem

The study focused on people aged 18 to 35 years. Severe cannabis users had significant higher neuromelanin -i signals that measured dopamine function, happy hormone-in specific brain regions associated with the severity of psychosis.

This increase was more pronounced among people with more severe cannabis use disorder, showing a dose -related pattern.

It is not the first time that smoking weeds has been associated with a higher risk of psychosis.

For example, a 2024 study found that frequent use of high potential pots increased the chance of psychosis, independent of genetic predisposition.

“We hope that this research helps to inform young people about the potential risks associated with the harmful use of cannabis – especially those with a family history of psychosis or other factors that can increase their sensitivity,” said lead author Jessica Ahrens, a doctoral student in the integrated neuroscience program at McGill University.

Losing contact with reality?

A sudden finding was that those who had cannabis use disorder did not report more personal issues due to their weeds’ dependence – despite meeting all the criteria for the situation.

“This shows that individuals with a cannabis use disorder had a lower perception of damage despite the highest severity measured,” Ahrens said.

The findings are significant in the light of widespread marijuana legalization in NY, with regulators predicting the number of cannabis legal stores in NYC will double this year.

While it was good for business, critics say taking on the Ganja train has led to a subway crime in the city.

Despite his reputation to be the “safer” medicine, recent studies have also shown that smoking pot can increase the risk of your cancer and speed up aging.

“The biggest problem is that since it was a 1 narcotic schedule [in 1970]It has made it very difficult to do real, double, placebo-controlled studies, ”said Dr. Ken Weinberg, the leading medical medical officer of the New York Cannabis, previously told The Post.

“I don’t think there is enough data.”
