Easier access to concealed firearms is associated with significantly higher rates of handgun-related homicide, according to a new study.

Once again, “researchers”, either incompetent or by political agenda, mistake correlation with causality.  Dangerous neighborhoods beget law-abiding people to request concealed carry permits for their protection.  It is the dangerous neighborhoods that are the causal factor.  Concealed carrying citizens do not make neighborhoods dangerous.

Look no further than Chicago, where obtaining a concealed carry permit is virtually impossible.  Chicago has the strictest gun laws in the country, yet the highest homicide rates.  That example, alone, should tell the reader that this “study” is manure; pure garbage.

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.

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.

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.

Researchers have found regular and occasional cannabis use as a teen is associated with a greater risk of other illicit drug taking in early adulthood. The study also found cannabis use was associated with harmful drinking and smoking.

It is amazing that this garbage gets published.  It would be akin to “Blind Kids less likely to see as adults”.  What is the CAUSALITY?  This paper would lead naive readers to think that teen cannabis use causes illicit drug use in adults.  But, how about teens who hang with the wrong crowds, who have lack of parental involvement, who may be flunking classes, who may have lower IQs, who may be struggling in school, who may disregard laws and prudence and use illicit cannabis and other drugs as teens as well as other illicit drugs later in life?

Time and time again, follow-up studies disprove the implications when CAUSALITY is considered.  More often than not, socio-economic conditions and IQ’s are the underlying causal factors which drive various conditions mistakenly attributed to cannabis.

An increase in mean temperature of 0.5 degrees Celsius over half a century may not seem all that serious, but it’s enough to have more than doubled the probability of a heat wave killing in excess of 100 people in India, according to researchers.

This is not on my usual topic, but illustrates bad science clearly, and the difficulty that “scientists” have discerning causality, even in formerly reputable schools.  Here, it says that the mean temperature CAUSES the likelihood of occasional heat waves.  Hello– isn’t it quite apparent that the occasional heat waves are what increase the mean temperature???

Let me illustrate:  Suppose we have a stable mean of 100, but a one time spike of 120:  100, 100, 100, 100, 100, 100, 100, 120, 100, 100.  That one spike to 120 increased the mean from 100, to 102.  In other words, the heat wave raised the mean, not the implied vice versa.  And this also does not mean that the heat wave caused the mean– only that the mean and the occasional heat spikes are correlated.  So called “scientists” often confuse correlation with causality, as shown so often in cannabis studies.

In the first prospective study of synthetic cannabinoids or SCs — the group of chemicals that mimic the effects of marijuana — researchers have found that symptoms of depression, drinking alcohol, or using marijuana was linked to an increased risk of SC use one year later.

Do you even have to read this garbage to know what it means?  It can be summarized as “DEPRESSED TEENS MORE LIKELY TO USE INTOXICANTS”, which isn’t science or news, but simply common sense.  But, to their credit, they did say:

“With respect to mental health, the researchers found that depressive symptoms, but not anxiety or impulsivity, were predictive of later [Synthetic Cannabinoids] use, suggesting that symptoms of depression may increase the likelihood of use. The same relationship between depressive symptoms and greater propensity for marijuana use was not found.

Alcohol and synthetic cannabinoids are much more powerful intoxicants and thereby provide greater escapes from reality, so this is no surprise.  But, the title of this paper implies that marijuana may be causal, so watch for lay journalists in the mainstream media to promote just that meme.
