Nearly half of American oncologists have recommended that their patients use medical marijuana, even though less than 30% consider themselves knowledgeable on the topic, according to a new survey by the Dana-Farber Cancer Institute in the Journal of Clinical Oncology.

Why it's happening: Ilana Braun, chief of Dana-Farber's Division of Adult Psychosocial Oncology, thinks that oncologists often find themselves succumbing to an uncomfortable position when their very ill patients request a therapy that's now legal across most of the country — even though its efficacy lacks strong scientific evidence.

Joe Biden's campaign released his 2019 tax returns on Tuesday, showing that he and his wife, Jill, paid nearly $300,000 in federal taxes last year.

Why it matters: The release, timed just hours before the first presidential debate, comes days after a bombshell New York Times report said that President Trump paid only $750 in federal taxes in 2016 and 2017. Biden's team is hoping to make the tax contrast a sticking point during their showdown.

New York City's coronavirus positivity rate has ticked up to 3.25%, its highest since June, Mayor Bill de Blasio said at a news conference on Tuesday.

Why it matters: The jump — from 1.93% on Monday — came on the first day that public elementary classrooms reopened in the city after months of closures, but guidelines state that all public schools will have to shut if the citywide seven-day positivity rate stays above 3%.
