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.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
