In Case You Were Wondering

The dangers of inhaling a cremated parent.

Earlier this week, Keith Richards of the Rolling Stones announced that he once snorted a mixture of his father's ashes and cocaine. Richards and his publicist later claimed that he was just kidding. But if he did snort his dad, would that have been unhealthy?

Only if he made a habit of it. There are diseases and conditions that can occur from getting small particles in your lungs, but they develop after repeated exposure—for instance,

coal miner's lung occurs after years of breathing in coal dust. Experts say Richards should be more concerned about the health effects of the cocaine, his cigarette smoking, and past drug use.

Snorting a cremated body could cause irritation if the ashes got into the respiratory system. Water-soluble substances, like

cocaine, can be absorbed through the mucous lining of the sinuses. But human remains would pass straight through the nose and could hypothetically make it into the lungs. Still, the odds are good that most, if not all, of the ashes would simply get swallowed or sneezed out of Richards' body.

Luckily for Richards, the cremated remains wouldn't have included any big bone fragments that might get stuck in his nose and obstruct his breathing (or interrupt the snorting process). His father's body would have spent a few hours in a 1,400- to 1,800-degree cremation chamber, and then the ashes would be run through a processor, like a giant blender, to give them a uniform texture and smooth out any remaining bone fragments. Magnets help remove any metal objects—like surgical pins or shrapnel—from the ashes.
