LYNGBY, DENMARK — A driver’s risk of being severely injured in an accident is highest after having either consumed alcohol alone, resulting in a blood/alcohol level above .08, or in combination with other psychoactive substances, according to the findings of a population-based case-controlled study published online in the journal Accident Analysis and Prevention. Danish researchers assessed the overall […]

As marijuana reform sweeps the United States, more users than ever are toking up in the comfort of their own homes. But even in places were there are no legal issues with using marijuana, such as the 19 states that allow the medical use of marijuana, or the two that have legalized adult recreational use, marijuana smokers still typically prefer to keep their sessions private, and, out of respect for neighbors, try to confine the smell of cannabis use to their homes or apartments.
But how is the best way to toke discretely in the privacy of your own home, without the sweet smell of sensimillia wafting to your neighbors nose? A new study commissioned by Airfilters.com tries to find the answer.
The study analyzed the particulates in the air after marijuana was consumed in a central location, using various methods to puff. The particulates were then analyzed using a Fluke 985 Particle Counter to determine which smoking methods were the worst for indoor air quality by measuring particles ranging from .3 microns to 1 micron in size.
Puffs were taken using the following standard methods of marijuana consumption: joint, bong, bowl, and vapor. . . . . READ MORE
PHILADELPHIA, PA — Cannabis consumption is associated with mitigated symptoms of opiate withdrawal in subjects undergoing methadone maintenance treatment, according to the findings of a new study published online in The American Journal on Addictions.
Investigators at the Farber Institute for Neurosciences at Thomas Jefferson University in Philadelphia assessed the use of cannabis in 91 opiate-dependent subjects undergoing methadone maintenance treatment. Researchers found that subjects seeking methadone treatment who acknowledged a history of cannabis use reported “significantly less daily expenditure on acquisition of opiates.”
Authors additionally reported that subjects’ use of cannabis during treatment was associated with less severe symptoms of withdrawal on the clinical opiate withdrawal scale (COWS), an index designed to serve as an objective measure of opiate withdrawal. “[I]ncreased cannabis use was found to be associated with lower severity of [opiate] withdrawal in a subset of the sample with available chart data,” authors wrote. “These results suggested a potential role for cannabis in the reduction of withdrawal severity during methadone induction.”
They concluded, “The present findings may point to novel interventions to be employed during treatment for opiate dependence that specifically target cannabinoid–opioid system interactions.”

Pulmonary complications associated with the regular smoking of cannabis are “relatively small” and far lower than those associated with tobacco smoking, according to a recent review published in the June edition of the scientific journal Annals of the American Thoracic Society.
The paper – authored by Donald P. Tashkin, MD, emeritus professor of medicine and medical director of the Pulmonary Function Laboratory at the David Geffen School of Medicine at University of California, Los Angeles – is “the most comprehensive and authoritative review of the subject ever published,” according to an accompanying commentary. Donald Tashkin conducted US-government sponsored studies of marijuana and lung function for over 30 years.
His review finds that although smoking cannabis may be associated with symptoms of chronic bronchitis, studies do not substantiate claims that it is positively associated with the development of lung cancer, chronic obstructive pulmonary disease (COPD), emphysema, or bullous lung disease.
“[H]abitual use of marijuana alone does not appear to lead to significant abnormalities in lung function,” Tashkin writes. “[F]indings from a limited number of well-designed epidemiological studies do not suggest an increased risk of either lung or upper airway cancer from light or moderate use. … Overall. . . . .

LONDON — The inhalation of the non-psychoactive cannabinoid CBD (cannabidiol) significantly mitigates tobacco smokers’ desire for cigarettes, according to clinical trial data published online in the journal Addictive Behaviors.
Investigators at University College London conducted a double blind pilot study to assess the impact of the ad-hoc consumption of organic CBD versus placebo in 24 tobacco-smoking subjects seeking to quit their habit. Participants were randomized to receive an inhaler containing CBD (n=12) or placebo (n=12) for one week. Trial investigators instructed subjects to use the inhaler when they felt the urge to smoke.
Researchers reported: “Over the treatment week, placebo treated smokers showed no differences in number of cigarettes smoked. In contrast, those treated with CBD significantly reduced the number of cigarettes smoked by [the equivalent of] 40 percent during treatment.” Moreover, participants who used CBD did not report experiencing increased cravings for nicotine during the study’s duration.
Investigators concluded, “This is the first study, as far as we are aware, to demonstrate the impact of CBD on cigarette smoking…. These preliminary data, combined with the strong preclinical rationale for use of this compound, suggest CBD to be a potential treatment for nicotine addiction that warrants further exploration.”

MORGANTOWN, WV – THC possesses gastroprotective qualities and could potentially reduce incidences of NSAID (non-steroidal anti-inflammatory drugs)- induced hospitalizations, according to preclinical data published online in the European Journal of Pharmacology.
Investigators at West Virginia University assessed the impact of THC administration in an animal model of NSAID-induced gastric inflammation. They reported that low doses of THC provided gastroprotective effects, such as attenuating gastric hemorrhages and lesions, and reducing ulcers.
“The results of the present study suggest that delta-9-THC … may also possess gastroprotective effects in NSAID using patients. … As current antacid regimens may be associated with undesirable effects, … other approaches to prevent NSAID-induced gastric ulcers are needed. In addition to their gastroprotective effects, cannabinoids produce other beneficial effects, including pain reduction. … Thus, cannabinoids may have the added benefit of reducing the effective analgesic dose of NSAIDs, as well as reducing the incidence of NSAID-induced gastric ulcers.”
NSAIDs such as ibuprofren are among the most widely used analgesic substances in the world, but their consumption is associated with v. . . . . READ MORE
MORGANTOWN, WV — Non-steroidal anti-inflammatory drugs (NSAID), such as ibuprofen, are among the most widely used analgesic substances in the world. However, the consumption of these products is associated with various adverse and life-threatening side-effects such as heart-attack, stroke, and internal bleeding.
In fact, according to a 2001 analysis, in the United States alone, “gastrointestinal complications induced by non-steroidal anti-inflammatory drugs (NSAIDs) cause more than 100,000 hospitalizations and an estimated 16,500 deaths annually.”
Could these adverse gastrointestinal effects be offset by cannabis? A just published study in the European Journal of Pharmacology indicates that the most likely answer is ‘yes.’
Researchers at West Virginia University assessed the impact of THC administration in an animal model of NSAID-induced gastric inflammation. Investigators reported that low doses of THC provided gastroprotective effects, significantly attenuating gastric hemorrhages and lesions.
They concluded: “The results of the present study suggest that delta-9-THC … may also possess gastroprotective effects in NSAID using patients. … As current antacid regimens may be associated with undesirable effects, such as reduced bone density, increased risk of bacterial infection, and vitamin deficiencies. . . . .

LOS ANGELES, CA — A forthcoming review to be published in journal Annals of the American Thoracic Society reiterates that the ingestion of cannabis smoke poses nominal pulmonary risks compared to those associated with tobacco smoke.
The author of the paper, Donald P. Tashkin, MD, emeritus professor of medicine and medical director of the Pulmonary Function Laboratory at the David Geffen School of Medicine at University of California, Los Angeles performed US-government sponsored studies of marijuana and lung function for over 30 years.
A preview of Dr. Tashkin’s forthcoming review appears on the American Thoracic Society website. It reads:
Dr. Tashkin found that regular smoking of marijuana by itself causes visible and microscopic injury to the large airways that is consistently associated with an increased likelihood of symptoms of chronic bronchitis that subside after cessation of use. He also found that the evidence does not indicate that habitual use of marijuana leads to significant abnormalities in lung function when assessed either cross-sectionally or longitudinally, except for possible increases in lung volumes and modest increases in airway resistance of unclear clinical significance.
The author finds no clear link between marijuana use and the development of COPD or lower respiratory tract infections. In addition, “. . . . . READ MORE
GAINESVILLE, FL — The legalization of marijuana for medical purposes does not lead to an increase in teen marijuana use, according to a new study by researchers at the University of Florida College of Medicine in Gainseville.
The study, published in the American Journal of Public Health, used data collected from the Youth Risk Behavior Survey for the states of Montana, Rhode Island, Michigan, and Delaware compiled over an eight year period.
“Our results suggest that, in the states assessed here, MMLs [medical marijuana laws] have not measurably affected adolescent marijuana use in the first few years after their enactment,” researchers wrote in their conclusion. ”Longer-term results, after MMLs are more fully implemented, might be different.”
The study confirms the results of a similar studies conducted in years past, while contradicting public statements made by Drug Czar Gil Kerlikowske and other medical marijuana opponents, who repeatedly allege that the passage of medical marijuana laws is directly responsible for higher levels of self-reported marijuana consumption among U.S. teenagers.
A study conducted last year by researchers from Montana State University, the University of Oregon, and the University of Colorado, Denver examined the relationship between st. . . . . READ MORE
TABRIZ, IRAN – The consumption of hemp seed nutritional oil, in conjunction with the intake of evening primrose oils and a restricted diet high in hot-natured foods (such as pepper) and low in saturated fats and sugars, is associated with “significant improvement” in symptom management and immunological characteristics in subjects with multiple sclerosis (MS), according to clinical trial data published in the current issue of the scientific journal BioImpacts.
Researchers at the Tabriz University of Medical Sciences in Iran assessed the impact of hemp seed oil, evening primrose oils, and a restricted diet in 23 patients diagnosed with relapsing remitting MS. They reported that participants at the study’s completion “were healthier in comparison to baseline” and that “clinical and immunological parameters showed improvement in the patients after the intervention.”
Authors acknowledged that hemp seed oil possesses potent antioxidative properties and also likely acts on specific signaling pathways that regulate inflammatory responses – two characteristics that would presumably make it beneficial in the treatment of MS.
Authors concluded: “After six months, sig. . . . . READ MORE
