How To Talk About Medical Marijuana With Your Doctor Over the last decade, cannabis has had a moment. Thirty-six states and Washington D.C. have legalized it for medical use. (Fifteen states, plus D.C., have also legalized weed recreationally.) Altogether, about 5.5 million people in the U.S. now have medical marijuana cards. One of the primary arguments for expanding marijuana laws is the drug’s potential usefulness for medical treatments. While each state has its own rules for which conditions are eligible, issues like chronic pain are nearly universally accepted as a reason for using medical marijuana. But there’s still a large divide between the traditional medical establishment and the cannabis industry. Cannabis is still illegal federally, and a recent study showed that many clinicians feel they don’t know enough about medical marijuana to make a recommendation to patients. This in turn impacts how patients feel about talking to their doctor about using cannabis to treat medical conditions. Joining Ira to talk about the ins and outs of connecting cannabis to the larger medical establishment are Dr. Ziva Cooper, research director for UCLA’s Cannabis Research Initiative in San Francisco, California, and Dr. Donald Abrams, integrative oncologist and professor emeritus at University of California San Francisco’s Osher Center for Integrative Medicine. What Can Crayfish Tell Us About Drugs In Our Waterways? Wastewater is a grab bag of chemicals. There’s industrial run-off, bits of animal and viral DNA, and then there are compounds that trickle out from our households. The medicines we’re flushing down the toilet or releasing through urine are making their way into countless bodies of water. Antidepressants are one of the drugs that frequently end up in the environment. A team of scientists wanted to study the effects of these antidepressants on streams wending their way through ecosystems. So they looked to none other than the crayfish. They found that crayfish exposed to these drugs were a bit bolder. Their results were published this week in the journal Ecosphere. Freshwater ecologist Lindsey Reisinger and freshwater biogeochemist A.J. Reisinger, who are both authors on that study, talk about how these drugs affect crayfish and potential downstream effects on waterways and the ecosystem. We Aren’t Squidding Around—It’s Cephalopod Week 2021! The wait is over—Cephalopod Week 2021 is finally here. It’s Science Friday’s annual ceph-lo-bration of all things mostly-tentacled, and this year’s lineup of events is going to be ceph-tacular. Visit behind-the-scenes at the Monterey Bay Aquarium, play deep sea trivia, watch mini documentaries, chat with real scientists working with cephalopods every day, and a whole lot more. Diana Montano, SciFri’s outreach manager and emcee of the deep sea, joins Ira and Science Diction host Johanna Mayer to kick things off, with some trivia about the origins of squiddy words. Kids Are Benefiting From Adult Vaccinations, Too Something interesting is happening in some communities where most adults are vaccinated against COVID-19: infection rates in kids are going way down, too. Right now, Americans 12 and older are eligible for the vaccine, leaving the country’s youngest still exposed. So this is a promising sign, considering about two-thirds of U.S. adults have received at least one shot of a COVID-19 vaccine. But some experts are saying we still need to be cautious about throwing kids together again before they’re vaccinated. Joining Ira to chat about this story is Maggie Koerth, senior science writer at FiveThirtyEight in Minneapolis, Minnesota. They also talk about other top science stories of the week, including news that cicada broods might emerge more often with climate change. Subscribe to this podcast.
