In a study looking at brain scans of people with mild loss of thought and memory ability, researchers report evidence of lower levels of the serotonin transporter — a natural brain chemical that regulates mood, sleep and appetite.

A lay person, or a person intending to mislead, would jump to the conclusion that low serotonin levels cause dementia.  We constantly see that when article such as “Cannabis users have lower IQs” and “Teens who use cannabis less likely to succeed in life”, and other such nonsense.

I am happy to present this good quality example from Johns Hopkins by the simple phrase: “Previous studies from Johns Hopkins and other centers have shown that people with Alzheimer’s disease and severe cognitive decline have severe loss of serotonin neurons, but the studies did not show whether those reductions were a cause or effect of the disease. Results of the new study of people with very early signs of memory decline, the researchers say, suggest that lower serotonin transporters may be drivers of the disease rather than a byproduct.”

True, they may believe that the reductions are causal, based on other studies, but they do NOT jump to conclusions like so many biased cannabis reports that strike sour notes with me.   I wish more researchers were wiser and more forthcoming when finding correlations, when causality has not been established, instead of foisting propaganda and lies.

Marijuana use is associated with a three-fold risk of death from hypertension, according to new research.

No BS that I can detect!  This looks like a reasonable study that sought to exclude confounders, unlike so many poor-quality studies.  Apparently, the longer you use cannabis, the greater the chance for hypertension.

If anyone sees something I might have missed, please add a comment about it.

More than 130,000 Anterior Cruciate Ligament (ACL) surgeries take place each year with the majority of patients not requiring pain medication after three months post-operatively. However, researchers have found that those patients who were filling opioid prescriptions prior to surgery were 10 times more likely to be filling prescriptions five months after surgery.

That brilliance could be read, “Patients who have lower thresholds of pain and/or more extensive ACL damage,  are more likely to use opiates longer”.  Well, DUH!  Where is the causality?  Are people in greater pain more likely to take opiates before surgery, as well as for longer after?  This may be the causal factor vs the implication that if we withhold pain relief until after surgery, it will toughen people to do without pain relief quicker.  Puh-lease.  They are not determining the causal factor here.  Bad study.

NORML’s mission is to move public opinion sufficiently to legalize the responsible use of marijuana by adults, and to serve as an advocate for consumers to assure they have access to high quality marijuana that is safe, convenient and affordable.

Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice by scientists at the University of Bonn with their colleagues at The Hebrew University of Jerusalem (Israel). Old animals were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with a cannabis active ingredient. This opens up new options, for instance, when it comes to treating dementia.

The DEA must be upset.  Clearly, they ignore all the scientific evidence and pursue their own job-preserving ways, while they ruin people’s lives and stifle research.  And, Congress knows this (or are complete idiots) but has their lips firmly on Big Parma’s butt cheeks.  (Sigh)  When will we ever emerge from the dark ages?

Cannabis use is associated with reduced prevalence of obesity and diabetes mellitus (DM) in humans and mouse disease models. Obesity and DM are a well-established independent risk factor for non-alcoholic fatty liver disease (NAFLD), the most prevalent liver disease globally. The effects of cannabis use on NAFLD prevalence in humans remains ill-defined. Our objective is to determine the relationship between cannabis use and the prevalence of NAFLD in humans. We conducted a population-based case-control study of 5,950,391 patients using the 2014 Healthcare Cost and Utilization Project (HCUP), Nationwide Inpatient Survey (NIS) discharge records of patients 18 years and older. After identifying patients with NAFLD (1% of all patients), we next identified three exposure groups: non-cannabis users (98.04%), non-dependent cannabis users (1.74%), and dependent cannabis users (0.22%). We adjusted for potential demographics and patient related confounders and used multivariate logistic regression (SAS 9.4) to determine the odds of developing NAFLD with respects to cannabis use. Our findings revealed that cannabis users (dependent and non-dependent) showed significantly lower NAFLD prevalence compared to non-users (AOR: 0.82[0.76–0.88]; p<0.0001). The prevalence of NAFLD was 15% lower in non-dependent users (AOR: 0.85[0.79–0.92]; p<0.0001) and 52% lower in dependent users (AOR: 0.49[0.36–0.65]; p<0.0001). Among cannabis users, dependent patients had 43% significantly lower prevalence of NAFLD compared to non-dependent patients (AOR: 0.57[0.42–0.77]; p<0.0001). Our observations suggest that cannabis use is associated with lower prevalence of NAFLD in patients. These novel findings suggest additional molecular mechanistic studies to explore the potential role of cannabis use in NAFLD development.

You wouldn’t think chili peppers and marijuana have much in common. But when eaten, both interact with the same receptor in our stomachs, according to a new paper. The research could lead to new therapies for diabetes and colitis, and opens up intriguing questions about the relationship between the immune system, the gut and the brain.
