Boston Celtics guard Kyrie Irving has apologized to teammates for recent comments about their play, and the incident led him to also call and apologize to former teammate LeBron James for resisting his leadership efforts while they played for the Cleveland Cavaliers. "You go and you say something publicly, and it ends up received in so many different ways, and you never know how fragile or what guys are going through when you say things like that," Irving said.

Joe Walsh, Steven Tyler, Jason Isbell and other musicians who have suffered from addiction talk about the sometimes frightening transition to sobriety and the sources of creativity and hope they've discovered. "I think part of the process for me of sobering up, and I don't know that I've ever put it this way before or really thought about it this way before, was using my work to connect with the world that I had always felt so isolated from," says Isbell.

The effects of emotionally charged communication linger long after a message is delivered, writes David Nielson. He suggests considering the intended effect of a communication, taking a break and editing before sending and avoiding the visual crutch of bolding or underlining.

Gillette's "The Best a Man Can Be" advertising campaign is drawing comparisons to Nike's Colin Kaepernick campaign, but whereas Nike sought to reaffirm the values of its customers, Gillette is asking its audience to become different, Josh Barro argues. "[B]rands do not enjoy the corrective moral authority that might be enjoyed by a church or a family or a group of community elders to tell people that they are failing to live by the right values and should change their ways," he writes.

Why it matters: A county-by-county study released today found there is a correlation between the amounts of money pharmaceutical companies spent marketing painkillers to doctors and the number of opioid-related deaths in nearby counties. From a recap of the study by Wired:

"During the time period of the study, 2013 through 2015, the counties that reported more spending of ad money also had more doctors' prescriptions written and more overdoses from prescription painkillers. The association grew stronger as the amount of pharmaceutical ad money increased in each county."

It is important to note that correlation is not the same thing as causation. Plus, there are loads of pharmaceutical sales representatives who market prescription drugs responsibly and doctors who exercise extreme caution when prescribing them. But that being said, marketing works. If the US is serious about slowing the opioid epidemic, maybe more attention needs to be paid to how dollars are being spent at every point in the supply chain.
