What are drugs and poisons?

Introduction

Drugs and poisons controlled under the Drugs, Poisons and Controlled Substances Act 1981 and the Drugs, Poisons and Controlled Substances Regulations 2006 (available on theVictorian Legislation and Parliamentary Documents website) are defined under the Act as being in the Poisons Code or in the Commonwealth Standard (Standard for the Uniform Scheduling of Drugs and Poisons, Schedule 2,3,4,5,6,7,8 and 9 Poisons).

Only these defined substances are controlled. They include:

• prescription medicines
• pharmacy-only medicines

Ketamine

Ketamine is an anesthetic that has been approved for both human and animal use in medical settings since 1970; about 90 percent of the ketamine legally sold is intended for veterinary use. It can be injected or snorted. Ketamine is also known as "Special K" or "vitamin K".

Certain doses of ketamine can cause dream-like states and hallucinations, and it has become common in club and rave scenes and has been used as a date rape drug.

At high doses, ketamine can cause delirium, amnesia, impaired motor function, high blood pressure, depression, and potentially fatal respiratory problems.

Emergency room mentions of ketamine rose from 19 in 1994 to 396 in 1999.** Recent use has been reported more frequently among white youth in many cities, including Atlanta, Baltimore, Boston, Chicago, Minneapolis/St. Paul, Newark, New York City, Phoenix, San Diego, Texas, and Washington, DC.

Rohypnol

Rohypnol, a trade name for flunitrazepam, has been of particular concern for the last few years because of its abuse in date rape.

It belongs to a class of drugs knows as benzodiazepines. When mixed with alcohol, Rohypnol can incapacitate victims and prevent them from resisting sexual assault. It can produce "anterograde amnesia," which means individuals may not remember events they experienced while under the effects of the drugs. Also, Rohypnol may be lethal when mixed with alcohol and/or other depressants.

Rohypnol is not approved for use in the United States, and its importation is banned. Illicit use of Rohypnol started appearing in the United States in the early 1990s, where it became known as "rophies," "roofies," "roach," and "rope." Emergency room mentions of Rohypnol were 13 in 1994 and increased to 624 in 1998; they decreased to 540 in 1999.

GHB (gamma hydroxybutyrate)

Since about 1990, GHB has been abused in the U.S. for euphoric, sedative, and anabolic (body building) effects. It is a central nervous system depressant that was widely available over-the-counter in health food stores during the 1980s and until 1992. It was purchased largely by body builders to aid fat reduction and muscle building. Street names include Liquid Ecstasy, Soap, Easy Lay, and Georgia Home Boy. Even though GHB may be difficult to distinguish from water, it has appeared in law enforcement indicators, including seizures of large amounts in Minneapolis/St. Paul and Phoenix.

Coma and seizures can occur following abuse of GHB and, when combined with methamphetamine, there appears to be an increased risk of seizure. Combining use with other drugs such as alcohol can result in nausea and difficulty breathing. GHB may also produce withdrawal effects, including insomnia, anxiety, tremors, and sweating.

Rohypnol GHB and Ketamine

GHB, Rohypnol, and ketamine are predominantly central nervous system depressants. Because they are often colorless, tasteless, and odorless, they can be added to beverages and ingested unknowingly.

These drugs emerged a few years ago as "date rape" drugs. Because of concern about their abuse, Congress passed the "Drug-Induced Rape Prevention and Punishment Act of 1996" in October 1996. This legislation increased Federal penalties for use of any controlled substance to aid in sexual assault.

MDMA (Ecstasy)

MDMA is a synthetic, psychoactive drug with both stimulant (amphetamine-like) and hallucinogenic (LSD-like) properties. Street names for MDMA include Ecstasy, Adam, XTC, hug, beans, and love drug. Its chemical structure (3-4 methylenedioxymethamphetamine, "MDMA") is similar to methamphetamine, methylenedioxyamphetamine (MDA), and mescaline - these are synthetic drugs known to cause brain damage. MDMA usually is taken in pill form, but some users snort it, inject it, or use it in suppository form.

Many problems MDMA users encounter are similar to those found with the use of amphetamines and cocaine. Psychological difficulties can include confusion, depression, sleep problems, severe anxiety, and paranoia. Physical problems can include muscle tension, involuntary teeth clenching, nausea, blurred vision, faintness, and chills or sweating. Use of the drug has also been associated with increases in heart rate and blood pressure, which are special risks for people with circulatory or heart disease. Recent research also links MDMA use to long-term damage to those parts of the brain critical to thought, memory, and pleasure.
