Navy Video Is Disturbing Picture of Bath Salt Abuse Tonight we see the gritty reality of a new trend in drug use. The drug known as bath salts. There's a tape made by the us navy. And abc's chief global affairs correspondent martha raddatz tells us why the navy is sending out this video alert. Reporter: The video puts you inside the mind of the drug user. From the moment you inhale the potent powder, to what quickly follows. Your world descends into terror and paranoia. Your girlfriend, then your friend, suddenly become demons. And you? Erratic, violent, out of control before finally being sedated by an emergency crew. One of the most concerning things about bath salts is, these hallucinations, these paranoid delusions, they will last long after the intoxication is gone. Reporter: Bath salts have nothing to do with a relaxing bath. Illegal, but easy to get, it is an underground code name for the synthetic drug that acts like a super charged amphetamine, a trip that can have a deadly end. While the navy doesn't have hard numbers of abuse in their ranks, they are fearful. In 2011, 16 midshipmen at the naval academy were expelled after abusing another synthetic drug, same case at sea, in all some 400 sailors were forced out. Bath salts are the latest temptation. Sometimes like a college dorm, or fraternity house, sailors live together and they share a barracks room together and when someone does something, others can see it andte it. And so our goal is to nip this in the bud. Reporter: It's not just the video, the navy will now do random drug testing on sailors as an added precaution. They are taking this drug very seriously. What are the sailors saying about all this? I think some of them think the add is a little bit over the top. But they know this is a very serious problem. Here's a really interesting statistic. A military drug positive rate is four times lower than the general workforce. So the military, the navy, is very committed to preventing drug abuse. All right, martha raddatz, thanks so much.
