Well I guess there’s now a “scientific consensus” and “the debate is over” and the “science is settled” regarding the liberal-left’s hideous (but “progressive”!) efforts, led by General Jack Layton and Libby Davies of the you’ve got to be kidding party among other “progressives” in the Liberal Party, to push for the legalization or decriminalization of pot-smoking among our nation’s kids, as their way to attract the best and brightest to our country (and make Canada more like yummy Euroliberal Holland).
Or are they pot-smoking is bad “deniers”?
Doctors: Marijuana Triggers Psychosis
Study Used Brain Scans For First Time To Show Link Between Pot And Paranoia
(AP) New findings on marijuana’s damaging effect on the brain show the drug triggers temporary psychotic symptoms in some people, including hallucinations and paranoid delusions, doctors say.
British doctors took brain scans of 15 healthy volunteers given small doses of two of the active ingredients of cannabis, as well as a placebo.
One compound, cannabidiol, or CBD, made people more relaxed. But even small doses of another component, tetrahydrocannabinol, or THC, produced temporary psychotic symptoms in people, including hallucinations and paranoid delusions, doctors said.
The results, to be presented at an international mental health conference in London on Tuesday and Wednesday, provides physical evidence of the drug’s damaging influence on the human brain.
“We’ve long suspected that cannabis is linked to psychoses, but we have never before had scans to show how the mechanism works,” said Dr. Philip McGuire, a professor of psychiatry at King’s College, London.
In analyzing MRI scans of the study’s subjects, McGuire and his colleagues found that THC interfered with activity in the inferior frontal cortex, a region of the brain associated with paranoia.
“THC is switching off that regulator,” McGuire said, effectively unleashing the paranoia usually kept under control by the frontal cortex.
In another study being presented at the conference, a two-day gathering of mental health experts discussing the connections between cannabis and mental health, scientists found that marijuana worsens psychotic symptoms of schizophrenics.
Doctors at Yale University in the U.S. tested the impact of THC on 150 healthy volunteers and 13 people with stable schizophrenia. Nearly half of the healthy subjects experienced psychotic symptoms when given the drug.
While the doctors expected to see marijuana improve the conditions of their schizophrenic subjects — since their patients reported that the drug calmed them — they found that the reverse was true.

While D’Souza had intended to study marijuana’s impact on schizophrenics in more patients, the study was stopped prematurely because the impact was so pronounced that it would have been unethical to test it on more people with schizophrenia.
