In a new study, arteries in rats that inhaled secondhand marijuana smoke for one minute carried blood less efficiently for at least 90 minutes. Similar exposure to secondhand tobacco smoke caused blood vessel impairment for 30 minutes.
“While the effect is temporary for both cigarette and marijuana smoke, these temporary problems can turn into long-term problems if exposures occur often enough and may increase the chances of developing hardened and clogged arteries,” said Matthew Springer, Ph.D.
The legalization of recreational marijuana in Colorado was associated with both increased hospital visits and cases at a regional poison center because of unintentional exposure to the drug by children, suggesting effective preventive measures are needed as more states consider legalizing the drug, according to an article published online by JAMA Pediatrics
The authors identified 81 children – 62 included in the analysis – evaluated at the hospital and 163 marijuana exposure calls to a Colorado RPC. The median age of children who visited the hospital was 2.4 years and for children in RPC cases.
In June, 2016, the 2015 Healthy Kids Colorado Survey (HKCS) was released with the media claiming that past month marijuana use by Colorado teens had not increased since pot had been legalized and use was within line with the national average.
However, Rocky Mountain High Intensity Drug Trafficking Area asks, “Is the Healthy Kids Colorado Survey ‘Good News’ and is Colorado teen marijuana use ‘flat?’ The reader can examine the facts and data to make an informed decision. What is clear is that there is no overall pattern in the HKCS data: thus it is best to refrain from jumping to conclusions on such an important issue. The HKCS results are highly variable between class years and regions from major increases to major decreases.
Examples of variables include:
• There was a 57.5 percent increase in use among one region’s freshmen while a 53.4 percent decrease in another.
• In one region there was a 72.0 percent increase in high school sophomore use but, in another, a 38.9 percent decrease.
• One region for juniors shows a 49.8 percent increase and another, 33.1 percent decrease.
• In one region, high school seniors had a 90.0 percent increase and in another a 34.3 percent decrease.
Opioid abuse — which has spurred a 20-year high in heroin use in the U.S. — has become a significant cause of death nationwide.
In 2014, there were 28,647 deaths due to opioid overdoses. The overdoses were due to natural, semisynthetic and synthetic opioids, methadone and heroin.
A new study, Marijuana Exposure in Children Hospitalized for Bronchiolitis, found that one in six infants and toddlers admitted to a Colorado hospital with coughing, wheezing and other symptoms of bronchiolitis tested positive for marijuana exposure. There were comparisons made between before the legalization and after the legalization of marijuana.
A questionnaire given to parents asked whether anyone in the home smoked marijuana.
Of the children who were identified as having been exposed to marijuana smokers, urine samples showed traces of a metabolite of tetrahydrocannabinol (THC), the psychoactive component of marijuana, in 16 percent of them.

Colorado is concerned about extremely high levels of THC in their marijuana and marijuana products. Their average potencies are 17 percent for marijuana and 62 percent for marijuana concentrate products.
Josh Hindi, whose dispensary, Dabble Extracts, a concentrates company, “estimates his extracts test between 70 percent and 80 percent THC and cater(s) to patients who prefer the more potent product.”
For Josh, lowering THC limits “would remove concentrates in total from any kind of retail operation.”
There is no research available on these alarmingly high THC levels and its impact on brain development of adolescents. As a result, the Colorado state House has a proposed bill limiting THC potency of marijuana to 15 percent and 16 percent in marijuana products. Additionally, “It would require everything to be sold in a child-resistant, opaque, resealable package and would require edibles to be packaged and sold only in single-serving amounts.”
There is no consistent evidence of an association between the implementation of policies related to prescription opioids and increases in the rates of heroin use or deaths. Instead the heroin market forces, including increased accessibility, reduced price, and high purity of heroin appear to be major drivers of the recent increases in rates of heroin use.
This finding contradicts the White House claim that the huge increase in heroin overdose deaths---440 percent in the past seven years---is directly related to prescription pain killers and changes in prescribing policies aimed at making them harder to obtain and abuse.
The article appearing in the New England Journal of Medicine is a product of leading researchers at the National Institute of Drug Abuse, the Food and Drug Administration, and the Centers for Disease Control and Prevention. They surveyed dozens of recent, peer-reviewed studies on heroin use. Initiation patterns, overdose deaths and the effects of policy changes in prescribing opioids.
Marijuana use by Colorado teens ages 12 to 17 has increased 20% more in the two years since legalization. The data came from the National Survey on Drug Use and Health.
With the increase the state moved from number 4 to number 1 in teen pot use.
“With the legalization of marijuana it has just kinda made people more comfortable with being open about. It’s more socially acceptable, so I think people are more open about the fact that they use it,” said Studio A64 Owner Ambur Racek.
Marijuana use by adults in the United States has soared, more doubling, over the past decade, 2001-2002 to 2012-2013. Surveys show 9.5 percent of Americans use marijuana; 30 percent of users meet criteria for a disorder.
Past year marijuana use rose from 4.1 percent to 9.5 percent of the U.S. adult population, while the prevalence of marijuana use disorder rose from 1.5 percent to 2.9 percent, according to national surveys conducted by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health.
“Based on the results of our surveys, marijuana use in the United States has risen rapidly over the past decade, with about 3 in 10 people who use marijuana meeting the criteria for addiction. Given these increases, it is important that the scientific community convey information to the public about the potential harms,” said George Koob, Ph.D., director of NIAAA.
The Colorado School Safety Resource Center in Thornton, CO, held a Safe Schools Summit. Over 350 educators, first responders and school mental health professionals crowded into a conference room to learn about the impact marijuana legalization is having on the schools.
“It’s the No. 1 problem in schools right now,” said Lynn Riemer, president of ACT on Drugs, a nonprofit drug awareness and education organization.
Jeff Whitmore, from Bayfield School District, said, “At first, I thought it was similar to alcohol and that the kids would do it anyway and all that. But it’s like they’re disguising alcohol as Kool-Aid and marketing it to kids. These edibles are cookies and gummy bears, and they’re filled with high amounts of THC.”
