A popular drug
Ambien is by far the best-selling prescription sleep medicine in the U.S., followed by Lunesta and, even farther behind, drugs such as Rozerem and Sonata. And the popularity of Ambien and its generic version, zolpidem, has only grown in recent years.
A growing problem?
The misuse of prescription drugs is a serious and growing problem in the U.S. Many people don't think twice about sharing drugs they've been prescribed with friends or family members. And most of the time, people "borrowing" prescription drugs are using them for pain or to help them sleep, not to get high.
Although the practice appears to be relatively rare, there are people out there who do take Ambien recreationally.
