Young people with cannabis dependence have altered brain function that may be the source of emotional disturbances and increased psychosis risk that are associated with cannabis abuse, according to a new study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. 
"Interestingly, the hyperconnectivity was strongest in the individuals who began using cannabis in early adolescence," said Dr. Manza, which lines up with reports of a higher risk of psychiatric problems when cannabis use begins early in life. Adolescence is a critical period of brain development, making early use of cannabis particularly detrimental. According to Dr. Manza, the measurement of resting brain activity is a relatively easy and non-invasive procedure, so the approach could be a useful measure for tracking the development of psychiatric symptoms with cannabis use.

New research reveals that several species, including the northern spotted owl, are succumbing to rat poison from thousands of "unpermitted private marijuana grow sites" in the northwestern California counties of Humboldt, Mendocino and Del Norte.
It's the contamination of the owls' primary food source — mice and rats, which, like humans, are attracted to the aromatic crop — that has been the animals' undoing: Scientists from the University of California, Davis, and the California Academy of Sciences have detected traces of anticoagulant rodenticide in seven of the 10 northern spotted owl carcasses they collected, according to a study published today (Jan. 11) in the journal Avian Conservation and Ecology.

A team of law enforcement agents from the U.S. Forest Service, local police and the U.S. Fish and Wildlife Service hike deep into the Plumas National Forest to help with cleanup and protect scientists who are studying illegal marijuana grow sites. Even after a site has been raided, growers can return. The nets are for helicopters that will lift tons of garbage out of the site. On this reclamation trip, teams ultimately cleaned up about 7 tons of garbage, 4,000 pounds of fertilize, and 4 miles of irrigation tube, and they found the carcasses of three black bears, one grey fox and several rodents and birds. This accounts for just four sites.

Marijuana has both short- and long-term effects on the body.
Within a few minutes of smoking marijuana, a person feels the effects of pot, as THC is rapidly passes from the lungs into the bloodstream, making its way to the brain and other organs.
What causes the “high” people experience is marijuana’s effect on over-activating parts of the brain containing specific brain cell receptors. This leads to feelings of an altered sense of time, other altered senses, changes in mood, impaired body movement, impaired memory and difficulty in thinking and problem-solving.
Researchers are still studying the long-term effects of marijuana. But what is known is that the younger a person begins using pot, such as in the teen years, the greater the declines in general knowledge, impaired thinking, learning difficulties and lowered IQ.

“Every statistical study has seen an increase in marijuana use,” he said. “There has been an increase in youths going to rehab for addiction to marijuana. There have been increases in car accidents. There has been an increase in fatalities related to marijuana. There has been an increase in workplace incidences related to marijuana and a decrease in productivity. And there has been an increase in robberies.”
“There has been nothing good for Colorado, except for maybe the increased tax revenue. But even then, it is a mixed bag. Many people have moved to Colorado to exploit legalized marijuana — so housing prices have increased. There is more traffic downtown. You can find marijuana dispensaries all over the place, especially in the poorer parts of town. It is becoming part of the state’s subculture,” said Brugger.
The smell of marijuana is ubiquitous in the state now — so much so that there has been a marked increase in complaints to the police about the smell.
For those who own ski resorts, the emergence of marijuana smokers has been troubling, according to Brugger.

"Positive" urine testing for Cannabis is associated with increased risk of traffic crashes

Although recent Cannabis use is widely reported to be associated with drug-related traffic accidents, the evidence that Cannabis users show an increased risk of being involved in road crashes is still not unequivocally proved. The purpose of the present work is to provide an objective assessment of this hypothesis, by comparing the frequency of occurrence of positive urine analyses in drivers involved in traffic accidents (n = 1406) with that observed in a control population undergoing mandatory urine drug testing (n = 1953). Urine analyses for drugs of abuse were performed by screening immunometric techniques followed by confirmation with UHPLC-QQQ MS, adopting a cut-off concentration for THC-COOH of 15 ng/mL. A case was classified as "positive" when a driver admitted to hospital for road traffic injuries showed urine concentrations of THC-COOH higher than the cut-off. All samples showing positive results for any other controlled drug in urine or blood alcohol concentrations >0.5 mg/mL were excluded from the study. Subjects positive to THC-COOH, and negative to all the other tested substances were 116 in Group 1 (8.2%) and 16 in Group 2 (0.8%). Subjects resulting negative to any tested substances were 1290 in Group 1 and 1937 in Group 2. The frequency of THC-COOH detection in the two groups was compared by using the "chi square" test, which resulted = 119.57, i.e. highly significant (P <<< 0.01). The Odds Ratio of the two groups was =10.88, showing a high degree of association between the presence of THC-COOH in urine and the occurrence of traffic accidents (P < 0.0001). The presented data, proving a high degree of association between Cannabis use and the occurrence of traffic accidents with injuries of the driver, support the use of urine testing for Cannabis in the procedures for the issuing of the driving licence, particularly in the case of subjects formerly or presently using Cannabis. This finding looks even more relevant in the present times, because of the increasing success of the policies of legalization of Cannabis for medical and non-medical purposes.

But she didn't have cancer. She had an obscure syndrome called cannabinoid hyperemesis syndrome, a condition only recently acknowledged by the medical community. It affects a small population — namely, a subset of marijuana users who smoke multiple times a day for months, years or even decades.

 

There's no hard data on the prevalence of the illness. But in California and Colorado, which have loosened marijuana laws in recent years, some emergency physicians say they're seeing it more often. One study in Colorado suggests there may be a link.

“Legalization will NOT stop the crimes committed by users who have no jobs to support their habits and prey upon you and I to get that money for their hit/fix.”
And while marijuana may very well have medicinal purposes, it’s not just the drug that makes our controlled substances dangerous and a significant crime and socio-economic issue in our country. The people involved in the illegal operations where drugs (including marijuana) are grown/produced, trafficked and transported, distributed to the TENS of THOUSANDS of dealers and MILLIONS of customers, are NOT good people! THOUSANDS of people are viciously murdered in Mexico every year as organizations vie for control over the markets and territory. 

Can Marijuana Help Addicts Kick Opioids?

November 16, 2017 - 20:39
Article Date: Thursday, November 16, 2017Thursday, November 16, 2017

According to research published earlier this month in the American Journal of Public Health, Colorado’s legalization of recreational marijuana in 2014 coincided with a 6.5 percent reduction in opioid overdose deaths. The researchers studied the opioid overdose rate in the state from 2000 to 2015, and found that after 14 years of a steady rise in opioid overdose deaths, the rate decreased by an average of 0.7 deaths per month.
 
My response:
The  study failed to account for the following:
•             Increased public education about the dangers of opioid prescribing (In 2014, 10.3% of patients received high-dose opioid prescriptions which was reduced to 8.7% in 2016)
•             Use of PDMP  (The rate of multiple provider episodes per 100,000 residents decreased from 60 in 2014 to 32 in 2016)
•             Wider distribution of the overdose-reversing drug naloxone (2011: 997 to 2015: 3,393)
•             Move from Rx opioids to heroin (Heroin overdose deaths increased 50% from 2014 to 2016 while opioid deaths decreased 12%.) Failure to quantify the impacts of the above make it unlikely any researcher could separate out the impacts of all of                them from another potential factor.
 
In addition, there is legitimate research that shows that marijuana use primes the brain for opioid addiction.

there is incomplete evidence of the efficacy and safety of medical use of cannabis in the clinical contexts considered in this review. Furthermore, for many of the outcomes considered, the confidence in the estimate of the effect was again low or very low. To give conclusive answers to the efficacy and safety of cannabis used for medical purposes in the clinical contexts considered, further studies are needed, with higher quality, larger sample sizes, and possibly using the same diagnostic tools for evaluating outcomes of interest.
