Cast of Vices / Atelier Vieux Carré

If you pop one of these (on your finger) and go numb, well, maybe you need a bigger size. For a safe dose of benzodiazepines, nicotine and other substances, check out L.A.'s Cast of Vices.

Bonus link:
Florida's Atelier Vieux Carré has a modernized version of the poison ring in 14k gold, with a well-hidden hinge that hides a compartment roomy enough for most pills.

Even more jewellery:

• Colleen Wolstenholme (Nova Scotia) - metal pills


• Aline Berdichevsky (Spain) - cool slabs


• Real Fake Watches (Germany) - leather bracelets
