CHICAGO — A so-called “smart drug” popular with young people may carry more of an addiction risk than thought, a small government study suggests.
Scans of 10 healthy men showed that the prescription drug Provigil caused changes in the brain’s pleasure center, very much like potentially habit-forming classic stimulants. Modafinil, the drug’s generic name, is sometimes used as an illegal study aid by college students.
“It would be wonderful if one could take a drug and be smarter, faster or have more energy,” said Dr. Nora Volkow, director of the National Institute on Drug Abuse, who led the study with a Brookhaven National Laboratory scientist. “But that is like fairy tales. We currently have nothing that has those benefits without side effects.”
The study, appearing in today’s Journal of the American Medical Association, may bust the myth that the drug is safe for healthy people, experts said.
Provigil is approved to treat excessive daytime sleepiness caused by narcolepsy. On the market since 1999, it’s the flagship product of Cephalon Inc. of Frazer, Pa., and its sales approached $1 billion last year. The company is developing a spin-off called Nuvigil.
Modafinil’s reputation as a brain enhancer stems from an Air Force study that found it improved the performance of sleep-deprived fighter pilots. College students buy and sell it illegally, as they do Ritalin and Adderall, to stay alert while studying.
Several scientists recently wrote in the journal Nature that healthy people should have the right to boost their brains with pills like Provigil. One author of that commentary, brain scientist Martha Farah of the University of Pennsylvania, said the new study “goes to show that we need a little caution and a little humility when we’re messing around with our brain chemistry.”
