The people of Central Asia smoke marijuana during rituals 2,500 years ago

Science
June 12 (UPI) -- Today, marijuana is the most popular drug in the world, but little is known about when and how humans first began taking advantage of its psychoactive properties. New research suggests the people of Central Asia were smoking marijuana as early as the first millennium B.C. Scientists were able to identify THC preserved in funerary incense burners recovered from an ancient cemetery in the Eastern Pamirs, an extension of the Himalayas. Researchers didn't set out to study early cannabis use. Instead, they were interested in analyzing the early use of wooden burners in funeral rituals by the ancient inhabitants of the Pamir Mountains. But spectral analysis of chemicals on the burners matched the signature of cannabis. What's more, the ancient marijuana remains featured elevat...

Mexico City issues emergency alert as wildfire smoke fills air

World
May 14 (UPI) -- Mexico City's environmental officials issued an emergency alert Tuesday as nearly two dozen fires worsened poor air quality in the region. The Environmental Commission of the Megalopolis urged residents to avoid outdoor activities, and infants, the elderly and those with respiratory illnesses to stay indoors entirely. The city's IMECA air quality index increased from 144 to 158. The index includes five levels on a scale from zero to more than 200. Zero to 50 is "good," 51 to 100 is "regular," 101 to 150 is "bad," 151 to 200 is "very bad" and more than 200 is "extremely bad." Firefighters are attempting to contain the wildfires, but to help reduce pollution in the city, officials asked residents to reduce emissions from vehicle use and notify authorities of any activities t...
SpaceX capsule suffers ‘anomaly,’ smoke seen for miles

SpaceX capsule suffers ‘anomaly,’ smoke seen for miles

Technology
Officials say SpaceXs new capsule for astronauts suffered an anomaly during a routine engine test firing in Florida, causing smoke to be seen for miles. Forty-fifth Space Wing Spokesman Jim Williams tells that the anomaly happened Saturday at Cape Canaveral Air Force Station while the SpaceX Crew Dragon capsule was undergoing a static test fire. Williams says no one was injured and the anomaly was contained. SpaceXs Crew Dragon successfully flew without a crew to the International Space Station in March. Officials had previously said the first flight with astronauts could be as early as this summer, but the schedule is under review. In a statement, SpaceX said its committed to ensuring that its systems meet rigorous safety standards. It says it is investigating why the anomaly oc...
California wildfires: The best smoke masks that protect against poor air quality

California wildfires: The best smoke masks that protect against poor air quality

Health
This is a Kaiser Health News story. Toby Lewsadder stepped outside an Ace Hardware store wearing a simple one-strap dust mask. He knew it wasn’t the right defense against the wildfire smoke lingering in the air, but it was all he could find. The local hardware stores he checked Tuesday didn’t have the more substantial respirator mask that public health officials recommend to defend against the harmful wildfire smoke that is blanketing communities across the state. One pharmacy he contacted was selling surgical masks for only a quarter. “No one has them,” said Lewsadder, 41, who was visiting the state capital from Los Angeles for an IT conference. So, for now, the dust mask would have to do: “Something is better than nothing,” he said. Unfortunately, ...
Secondhand smoke poses greater risks for teens: Study

Secondhand smoke poses greater risks for teens: Study

Health
More than 1.1 billion adults worldwide smoke cigarettes and, though laws that limit public and workplace smoking are lessening the amount of exposure to the public, an estimated 9.6 million U.S. adolescents are exposed to tobacco smoke, according to the Center for Disease Control and Prevention. Since the 1960s, researchers have been looking at the health effects of secondhand smoking and have linked this exposure with an increased likelihood of getting ear infections, lung infections and even contributing to poor lung development in small children. Additional research has demonstrated secondhand smoke exposure in children both increases the likelihood of suffering from asthma and worsens the severity of it in children afflicted by this condition. Researchers from the University of...
