Stone Cold Dealer

I love it when I understand NEJM enough that it makes me laugh.  This is about a case of 8 young people who showed up with what seems like lead poisoning, but the health authorities could not identify the source of lead.  Until...

After 8 weeks, we detected a common pattern: the patients were young, were unemployed or were students, had a history of smoking, and had body piercings. On questioning, all the patients eventually conceded that they were regular users of marijuana smoked in "joint" form or with the use of a water pipe.

It's sad that someone tainted their marijuana, but I love that characterization of potheads.  The authorities were eventually able to track this whole thing down and treat lots of other people who got sick.
