Substance abuse risk not greater in those using medical marijuana with prescribed opioids
2015-05-18
(Press-News.org) PISCATAWAY, NJ - Among people who use medical cannabis for chronic pain, those who also take prescription pain medications are not at increased risk for serious alcohol and other drug involvement, according to a study in the May issue of the Journal of Studies on Alcohol and Drugs.
Although medical cannabis is being used increasingly often as an alternative to opioids for chronic pain, in many patients it is being used in conjunction with opioids. This use has raised concerns that the combination could increase the risk of patients using substances such as alcohol and other drugs as well.
In this study, researchers looked at data from 273 patients at a medical cannabis clinic in Michigan. More than 60 percent of the participants reported also using prescription pain medication within the past month. There were no significant differences in the rate of co-occurring substance use between those who used prescription pain medication and those who did not.
This intersection of medical cannabis and prescription pain medication has not been widely studied, but the results still surprised the researchers, says lead study author Brian Perron, Ph.D., of the School of Social Work at the University of Michigan.
"We expected that persons receiving both cannabis and prescription opioids would have greater levels of involvement with alcohol and other drugs," Perron said. "However, that wasn't the case--although persons who were receiving both medical cannabis and prescription opioids reported higher levels of pain, they showed very few differences in their use of alcohol and other drugs compared to those receiving medical cannabis only."
Overall, subjects in the study reported higher rates of alcohol and other (noncannabis) drug use, both in their lifetime and in the past three months, than in the general population. But use of other drugs--including alcohol, cocaine, sedatives, street opioids, and amphetamines--did not differ between medical cannabis users who took prescription pain medications and those who did not.
Because prescription pain medications carry a more serious risk of addiction or overdose, medical cannabis may be a safer alternative in pain management, assuming that cannabis has efficacy for longer-term analgesia and is used as intended, according to Perron. But communication between doctor and patient is key.
"We actually know very little about who is receiving both medical cannabis and prescription pain medications," said Perron. "Physicians do not actually 'prescribe' medical cannabis--they only certify whether the patient has a qualifying condition, which allows the patient to gain access to medical cannabis. The system of dispensing medical cannabis is completely separate from prescription medications, so physicians may not know whether a given patient is using medical cannabis, how much, and in what form."
Perron points out that this was an observational study, so inferences must be made carefully. But he does conclude that it is important that health care providers become knowledgeable about medical cannabis laws and can have open conversations with their patients, especially as more states give access to cannabis for medical and recreational purposes.
"Managing a pain condition ultimately requires open communication between the health care professional and the patient," said Perron.

Shift work can affect your health
2015-05-18
New York, NY, May 18 2015 -- Shiftwork is an occupational health risk of growing significance because it is becoming more common and because of its potential influence on health outcomes, possibly increasing health differences between workers of higher vs lower socioeconomic status. A new study from the University of Wisconsin School of Medicine and Public Health determined that employees who work shifts outside of a 9-to-5 schedule are more likely to be overweight and experience sleep problems, and possibly more likely to develop metabolic disorders, such as diabetes, ...
Study validates effectiveness of genomic test for lung cancer detection
2015-05-18
(Boston) -- A new test co-developed by a Boston University School of Medicine (BUSM) researcher will allow patients suspected of having lung cancer to be subjected to fewer and less-invasive tests to determine if they have the disease.
"We are seeing an increase in the number of lesions suspicious for lung cancer found on chest imaging of current and former smokers. In the past, these patients have been subjected to invasive tests when traditional bronchoscopy tests prove inconclusive. Today's announcement provides physicians and patients with an additional piece of scientifically ...

Regular aspirin use may slow progression of early emphysema
2015-05-17
ATS 2015, DENVER -- Regular use of aspirin may help slow the progression of early emphysema, according to new research presented at the 2015 American Thoracic Society International Conference.
"Other than smoking cessation and avoidance, there are no known methods for reducing the risk of developing emphysema," said researcher Carrie Aaron MD, of the Columbia University Medical Center in New York. "In our large general population sample, we found that regular aspirin use (three or more days per week) was associated with a slower progression of percent emphysema on computed ...
Newer method of oxygen delivery for patients at risk of respiratory failure after surgery
2015-05-17
A relatively new, easier to implement, and better-tolerated method to provide supplemental oxygen to patients at risk of respiratory failure after surgery did not result in a worse rate of treatment failure compared to a more commonly used method, according to a study appearing in JAMA. The study is being released to coincide with its presentation at the American Thoracic Society 2015 International Conference.
After cardiothoracic surgery, acute respiratory failure is common and associated with an increased risk of illness and death. When low-flow oxygen therapy is insufficient ...
Potentially hazardous effects of mechanical and chemical characteristics of e-cigarettes
2015-05-17
ATS 2015, DENVER -- Unlike standard cigarettes, the components of electronic cigarettes are not regulated and standardized, thus they vary widely between products. The characteristics of these e-cigarette elements, including their delivery systems, combustion apparatuses, and the composition of the nicotine solutions they contain may affect the levels of potentially hazardous substances in the vapor they produce, according to a new study presented at the 2015 American Thoracic Society International Conference.
"While the chemical compositions and negative health effects ...
One exposure to e-cigarette use diminishes cough reflex sensitivity
2015-05-17
ATS 2015, DENVER -- With just one exposure to electronic-cigarette (e-cigarette) vapor, participants in a study of 30 healthy subjects demonstrated a diminishment of cough reflex sensitivity. The study was presented at the 2015 American Thoracic Society International Conference.
"Although e-cigarettes have become popular worldwide, very little is known about their effect on the respiratory system. There has been no other research to our knowledge on the effect of e-cigarette use on the sensitivity of the cough reflex," said lead author Peter Dicpinigaitis, MD, Professor ...
