Secondhand Smoke From Bongs Worse Than From Cigarettes: Study

USA Today: Cannabis, Marijuana Bong Smoke More Dangerous Than Cigarettes: Study
You’ve heard about the dangers of secondhand cigarette smoke, but what about secondhand bong smoke? The haze after a bubbly bong hit may appear harmless, but a new study published Wednesday in JAMA Network Open found bystanders may be inhaling air pollutants at concentrations more than twice federal air quality limits. Researchers at the University of California, Berkeley, measured fine particulate matter (PM2.5) in a real-world setting where a group of young adults socially smoked cannabis with a bong for two hours in an ordinary household living room. An aerosol monitor was placed where a nonsmoker might sit, recording PM2.5 levels before, during and after eight sessions. (Rodriguez, 3/30)

San Francisco Chronicle: Bong Smoke Is Worse Than Secondhand Tobacco Smoke, UC Berkeley Study Finds
Turns out that the lasting stink of bong water spilled onto the carpet is not the only danger to smoking marijuana through a tall tube cooled by water at its base. A study conducted at the UC Berkeley School of Public Health and published by the journal JAMA Network Open on Wednesday declared that secondhand cannabis smoke released during bong hits contains fine particulate matter at a concentration dangerously higher than that released by secondhand tobacco smoke.

Stat: Obesity Can Turn Helpful Drug Into Harmful One, Mouse Study Shows 
Researchers have long known that obesity rewires the immune system. Now a new study suggests these effects can be so profound they could turn a drug meant to treat a common inflammatory disease into one that makes things worse. Scientists discovered that mice with atopic dermatitis, a painful and itchy skin rash often triggered by an allergic reaction, were worse off if they were obese. A closer look at their immune responses led to a surprise finding: Different immune cell types drove the disease in obese versus lean mice. That caused a standard treatment to exacerbate symptoms in heavier animals, but adding another drug that made the immune response of the obese mice resemble those of lean animals made the treatment regimen work again.

WGCU: Researchers Continue Studying Possible Health Effects From Airborne Algae Toxins 
Researchers from Florida Gulf Coast University and Florida Atlantic University are studying the possible human health impacts caused by airborne toxins produced by blue-green algae through a study called "Cyanotoxins in Air Study." FGCU researchers are focusing on collecting the air sampling data, and researchers from FAU's College of Nursing and Harbor Branch Oceanographic Institute are working on the human health side of the study. They’ve been collecting air samples in Southwest Florida and across the state in Stuart. Researchers are asking volunteers who live near the water to provide blood, urine and nasal samples. There hasn’t been a major blue-green algae bloom for a few years so they’re collecting baseline data. (Kiniry, 3/30)

St. Louis Public Radio: She Gave Her Kidney To A High School Acquaintance — And It Changed His Life 
John “JT” Thomas was a healthy 20-year-old in 2011. But at that year’s family Thanksgiving gathering, he found that he couldn’t even finish his first plate of food. His appetite was gone — and he was increasingly lightheaded. His physicians had a chilling response to his symptoms, one that he recalls even today: “You shouldn’t be able to walk right now.” “It was a complete shock to the system,” Thomas recalled on St. Louis on the Air. Soon after, Thomas was diagnosed with focal segmental glomerulosclerosis, a disease in which scar tissue develops on the small parts of the kidneys that filter waste from the blood. (Woodbury, 3/30)
