Marijuana associated with same respiratory symptoms as tobacco

13.01.2005


Smoking marijuana is associated with increased risk of many of the same symptoms as smoking cigarettes--chronic bronchitis, coughing on most days, phlegm production, shortness of breath, and wheezing, according to a Yale study published in the Journal of General Internal Medicine.



In addition, marijuana smoking may increase risk of respiratory exposure by infectious organisms, such as fungi and molds, since cannabis plants are contaminated with a range of fungal spores, said Brent Moore, assistant professor of psychiatry at Yale School of Medicine and lead author of the study.

"Because more than two million adult Americans are heavy marijuana smokers, these risks represent a potentially large health burden," Moore said. "Marijuana smokers use more medical services for respiratory problems, and these demands are likely to increase as the population of heavy marijuana smokers ages."


The findings were based on 6,728 questionnaires completed by adult men and women, 20 to 59 years old, in 1988 and 1994. The data was from the National Health and Nutrition Examination Survey and was thought to provide the broadest snapshot to date of marijuana use and its effect on the lungs in a sample of U.S. citizens.

Current marijuana use was defined as self-reported lifetime use and use at least one day in the prior month. Seventy seven percent of marijuana smokers also smoked tobacco. The analysis statistically controlled for the number of cigarettes smoked per day. Individuals who smoked both marijuana and tobacco had increased rates of respiratory symptoms compared to those who smoked tobacco only.

"Our interest is in the additive effect of marijuana," Moore said.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
