Harvard Medical School’s Professor Clifford Woolf has proposed a radical way to combat drug abuse. He suggests using capsaicin to deter the abuse of certain extended-release drugs such as OxyContin and Ritalin.These morphine-based drugs, when taken as prescribed, release their opioids over time. But when crushed and snorted, swallowed or injected intravenously, they produce an intense high that is addictive.Woolf argues that adding capsaicin to the drug capsules is safe. If the capsules are swallowed whole, as prescribed, the patient would suffer no ill effects from the added capsaicin. But if it is crushed, anyone snorting or swallowing it would suffer from the exposed irritant.In an interview with the Harvard University Gazette, Woolf said "imagine snorting an extract of 50 jalapeno peppers and you get the idea."To date, the professor’s proposal is still in the preliminary stages of development and the additive is yet to enter the production stage.
