Use of the anti-anxiety drug Xanax has skyrocketed since 2006, with a shocking 44 million Americans getting prescriptions for it, according to a new survey. The drug is addictive and meant for short-term use only.

The survey, conducted by IMS, a marketing company for health-care products, found that Xanax use in the United States had gone up 29 percent in the last four years. To put that rise in perspective, the researchers noted that the population of the United States increased only 4 percent in those years.
