A recent study concludes that marijuana use might actually disrupt your sleep. However, experts point out there may be other factors involved.

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.

A study by neuroscientists finds that a non-psychoactive compound in cannabis called cannabidiol, or CBD, appears to protect against the long-term negative psychiatric effects of THC, the primary psychoactive ingredient in cannabis.

A new, widely reported study claims that marijuana poses significantly greater risks to cardiovascular health, particularly with regard to hypertension, than does cigarette smoking.Don’t believe the hype. A careful review of the study’s methods gives reason to pause.

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.

Adults in the UK who have poor sleep patterns are more likely to be overweight and obese and have poorer metabolic health, according to a new study.

This is another example of bad science: lack of causality.  Could poor eating habits contribute to poor sleep?  What about stressful jobs, contributing to both?  At least they admitted “Other studies have suggested that shortened sleep can lead to poor dietary choices.”

They also said, “Interestingly, the study did not find any relationship between shortened sleep and a less healthy diet — a fact that surprised the researchers.”  Well, what about an underlying stressor (work, life) making one eat excess “healthy diet” and poor sleep?  I could go on and on about this, but of course this is a summary and I haven’t the time to study the details of the methodology, but simply want to caution my readers about accepting others’ jumps to conclusions, and always consider CAUSALITY.
