If you've ever been to a rave, you've likely been offered Special K-but we're not talking about cereal here! Ketamine hydrochloride is a man-made anesthetic that moonlights under names like Special K, Kid-Rock, and K. Ketamine is available legally as an animal tranquilizer. When taken as a street drug, Special K can be snorted, swallowed, or injected. After doing K, you will likely feel as if you've had several cocktails. You may even feel like you're walking on marshmallows. Depending on how much you do, you may fall into what's known as a K-hole, where you'll feel detached from your body and be physically incapacitated. Many Special-K users experience nausea and cold sweats, particularly when the drug is taken at high doses. Because of its anesthetic properties, people on K may get hurt without realizing it. Recently, ketamine has been reported on the street as a "date-rape" drug. Large doses of K can induce unconsciousness and even cardiovascular failure. Although ketamine hydrochloride is available for medicinal purposes, it is illegal for recreational use.
