The true cost of cannabis: Why don't its illnesses, deaths command media headlines?

I've covered things that injure, sicken and kill kids and adults for more than 30 years. From auto safety to medical errors, I've competed to break stories on the latest deadly defect or health policy change, most recently on electronic cigarettes.

In late August, I added vaping-related lung illnesses to the beat. Last month, I added marijuana, psychosis and other mental illness.

It's a pretty solitary place to be.

We reporters covered the heck out of vaping lung illnesses starting in August. Once it became clear the culprit was THC and not nicotine, however, the news media seemed to lose interest, said former Food and Drug Administration chief Scott Gottlieb at a breakfast event I attended in early November.

Indeed, a search on the news archive Nexis shows that the number of stories mentioning "vaping" and "lung illness" went from 953 in September to 584 in the first 30 days of October, a nearly 40% drop.
