Does wearing two masks provide more protection?
It depends, but it’s possible that doubling up could help in some situations.
The U.S. Centers for Disease Control and Prevention recommends wearing a cloth mask made with two or more layers, and ensuring it covers your nose and mouth. The agency says it should fit snugly so there aren't any gaps at the sides of your face.
Wearing just one mask should be enough for most situations, as long as it fits well and isn't loose, said Dr. David Hamer, an infectious disease expert at Boston University.
“Starting out with a good mask to begin with is going to be key,” Hamer said.
Still, some people might want extra protection if they're at risk for severe illness if infected or will be in situations where they expect to be around others for extended periods, such as on a plane.
One option in scenarios when you want extra protection is to wear a cloth mask as well as a regular surgical mask, said Dr. Monica Gandhi, an infectious disease expert at the University of California, San Francisco.
Gandhi said that combination -- with either mask on top -- could help achieve a similar effect as the N95 mask. She recommended the added protection for people who will be indoors in areas where transmission rates are high — which could reflect the circulation of more contagious variants.
Another option Gandhi and a colleague recommend for situations where you want “maximum” protection: A two-layer cloth mask that has a filter material in between.
With single cloth masks for everyday use, Gandhi noted it's important that they're made of tightly-woven material and have at least two layers, which creates “an obstacle course” that makes it harder for virus-carrying particles to break through.

There's a dearth of research to back up the abundance of miraculous health claims tied to CBD ー but that won't stop celebrities from endorsing it. CBD, or cannabidiol, is a component of cannabis or hemp with little to no psychotropic effects. It is purported to have an array of applications to treat everything from epilepsy to anxiety, pain, depression, and sleeplessness. When Congress and President Trump signed the latest version of the Farm Bill into effect, they also legalized hemp, and thereby CBD derived from hemp.
More than 50 years after the psychedelic Summer of Love, psilocybin, the psychoactive component in magic mushrooms, is having a moment. Researchers at leading universities have been conducting research on the purported medical benefits of mushrooms for years, but as studies yield promising results, the opioid epidemic persists and sentiment warms toward cannabis, mushrooms are earning a lot more attention. Lawmakers and psychotropic advocates have concurrently advanced separate measures in Oregon, Colorado, and, most recently, Iowa, that attempt to loosen restrictions on these hallucinogenic fungi.
