Energy drinks first became popular in the United States in 1996 with the promise to "vitalize body and mind". They target young male teenagers who are exhausted from work. The drinks are heavily advertised through sponsoring extreme sports and Formula 1 racing. Red Bull gives out free samples from their cars. Some batches of Red Bull were found to contain small traces of cocaine. While energy drinks gain popularity, there are also health concerns like high blood pressure, stress, and questions around their long term effects.
