Club Drugs

Club drugs are group of psychoactive drugs. They act on the central nervous system and can cause changes in mood, awareness, and how you act. These drugs are often abused by young adults at all-night dance parties, dance clubs, and bars. They include

  • Methylenedioxymethamphetamine (MDMA), also known as Ecstasy XTC, X, E, Adam, Molly, Hug Beans, and Love Drug
  • Gamma-hydroxybutyrate (GHB), also known as G, Liquid Ecstasy, and Soap
  • Ketamine, also known as Special K, K, Vitamin K, and Jet
  • Rohypnol, also known as Roofies
  • Methamphetamine, also known as Speed, Ice, Chalk, Meth, Crystal, Crank, and Glass
  • Lysergic Acid Diethylamide (LSD), also known as Acid, Blotter, and Dots

Some of these drugs are approved for certain medical uses. Other uses of these drugs are abuse.

Club drugs are also sometimes used as "date rape" drugs, to make someone unable to say no to or fight back against sexual assault. Abusing these drugs can cause serious health problems and sometimes death. They are even more dangerous if you use them with alcohol.

Drug Reactions

Also called: Side effects

Most of the time, medicines make our lives better. They reduce aches and pains, fight infections, and control problems such as high blood pressure or diabetes. But medicines can also cause unwanted reactions.

One problem is interactions, which may occur between

  • Two drugs, such as aspirin and blood thinners
  • Drugs and food, such as statins and grapefruit
  • Drugs and supplements, such as ginkgo and blood thinners
  • Drugs and diseases, such as aspirin and peptic ulcers

Interactions can change the actions of one or both drugs. The drugs might not work, or you could get side effects.

Side effects are unwanted effects caused by the drugs. Most are mild, such as a stomach aches or drowsiness, and go away after you stop taking the drug. Others can be more serious.

Drug allergies are another type of reaction. They can be mild or life-threatening. Skin reactions, such as hives and rashes, are the most common type. Anaphylaxis, a serious allergic reaction, is more rare.

When you start a new prescription or over-the-counter medication, make sure you understand how to take it correctly. Know which other medications and foods you need to avoid. Ask your health care provider or pharmacist if you have questions.

ICD-10 Footnotes

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.

Present on Admission
The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement.
