This is part of an email that was sent around where I work. It was sent by someone who works in our substance abuse department. Hope it's helpful to some of you who have asked what certain names were for certain drugs your kids may be using. How would you know if you don't even know what that means? "It's very important that parents brush up on ... slang, because just like with text messaging, kids use all these abbreviations and parents dont know what they mean. But the more they understand what these things mean, the more they will be able to monitor kids behavior," says Gregory Pollock, a psychotherapist specializing in addiction at the Cleveland Clinic Foundation in Ohio. That's why WebMD went directly to the experts on the front lines of teen drug abuse to get a better handle on the today's teenage drug slang. Here's what you need to know about teens and drugs today: Cold Medicine Abuse Dextromethorphan (DXM): This is a drug contained in over-the-counter cough suppressants. After 900 milligrams, it becomes a hallucinogen. Synonyms for DXM include Candy, Dex, DM, Drex, Red Devils, Robo, Rojo, Skittles, Tussin, Velvet, Poor Man's X, and Vitamin D. "Tussin is a very popular name that has been catching on lately," says Pollock. "Cold medicine abuse is a very serious problem, from what I have seen, because it is so available." Syrup heads: Users of DXM Dexing: Abusing cough syrup. Synonyms include robotripping or robodosing because users tend to chug Robitussin or another cough syrup to get high. Triple C: This stands for Coricidin HBP Cough and Cold. "The triple C or CCC is something that we are seeing a lot of, and that is specific to Coricidin, but anything with DXM is abused today," adds Kevin M. Gray, MD, an assistant professor of psychiatry and behavioral sciences at the Medical University of South Carolina in Charleston. More Teen Drug Use Terms Special K: A medication used as an anesthetic in humans and animals, ketamine is sometimes abused as a "club drug." It can cause hallucinations and euphoria in higher doses. Synonyms include vitamin K, breakfast cereal, cat valium, horse tranquilizer, K, Ket, new ecstasy, psychedelic heroin, and super acid. Crank: The stimulant methamphetamine. Synonyms include meth, speed, chalk, white cross, fire, and glass. "Crystal methamphetamine is called ice," says Cleveland Clinic's Pollock. "Crystal meth is smoked, but meth can be injected, snorted, or taken as a pill," he explains. Antifreeze: Heroin. Synonyms include Big H, brown sugar, dope, golden girls, H, horse, junk, poison, skag, smack, sweet dreams, tar, and train, according to the web site of Phoenix House, a national alcohol and drug abuse treatment and prevention facility. Crunk: This is a verb that means to get high and drunk at the same time. Snow: Cocaine. Synonyms include Charlie, crack, coke, dust, flake, freebase, lady, nose candy, powder, rock, rails, snowbirds, toot, white, and yahoo, according to Phoenix House. "After all this time, alcohol and pot are still the most used drugs by teens, but cocaine is really a strong third, especially with females, because of the weight issue," says Janice Styer, MSW, a clinical coordinator-addictions counselor at Caron Treatment Center in Wernersville, Pa. "The drug of choice among women with eating disorders is almost invariably cocaine." A stimulant, cocaine can decrease appetite. X: Ecstasy or 3,4-Methylenedioxymethamphetamine (MDMA). Synonyms include Adam, E, bean, clarity, essence, lovers speed, MDMA, roll, stacy, XTC, according to the Phoenix House. Georgia Home Boy: This refers to Gamma Hydroxybutyrate (GHB), a central nervous system depressant can produce euphoric, sedative, and body-building effects. Other synonyms include Gamma-OH, Grievous Bodily Harm, Liquid Ecstasy, Liquid E, Liquid X, Organic Quaalude, and Scoop, according to Phoenix House. Roofies: This refers to rohypnol, a.k.a. the date rape drug. Synonyms include the forget pill, La Rocha, Mexican valium, R-2, rib, roachies, roofenol, rophies, roche (pronounced roe-shay), and rope. Kibbles and bits: The attention deficit hyperactivity disorder (ADHD) drug called Ritalin. It is sometimes also referred to as pineapple, says Pollock. Teens and Drugs on the Web Cheese: This is a hazardous mix of black tar heroin and Tylenol PM or other medicines containing diphenhydramine). It looks like grated parmesan cheese -- thus the name. There were more than 20 teen deaths in Dallas and surrounding neighborhoods that have been attributed to Cheese since it was identified in 2005. Candy flipping: This term refers to a high thats achieved by combining LSD (lysergic acid diethylamide) or acid with ecstasy. "The new thing, especially with kids on the Internet, is which drugs are best and safest to combine," explains Styer. A new study by the Caron Treatment Centers found that one in 10 messages on the Internet involved teens seeking advice from their peers on how to take illicit drugs. The messages were posted on common online message boards, forums, and social network sites such as MySpace.com. When it comes to teens and drugs, "You will never know everything, but you dont want your kids to think you are an idiot," Styer says. "You need to keep communication open and talk to your kids about the dangers of the Internet."
