Researchers have eased cocaine craving and withdrawal with a drug that triggers production of an important brain chemical partly depleted in chronic cocaine users. Cocaine use gradually reduces the brain’s supply of a chemical that certain brain cells use to communicate. The chemical, called dopamine, is believed to play a critical role in the pleasure centers of the brain, Dr. Todd Estroff said in a report at a Dallas seminar.
