Drug Guide: Definitions and Effects of Popular Types

To ensure teens aren't experimenting with dangerous substances, parents need to be aware of what's out there. Here's a roundup of the top popular drugs among kids.

Parental involvement is key to keeping kids from trying drugs – and talking to kids about the dangers of drugs is one of the first steps in doing so. But in order to start the anti-drug dialogue with your teen, it’s important to be educated on today’s popular and prevailing drugs.

As highlighted in the August 2012 Metro Parent article about teens and drugs, which covered the recent K2 ban and other drug trends, there will always be a “drug of the day.”

So – what the heck are salvia, Rohyphnol and kreteks? Learn about these, and other drugs here in our guide. All information below is from U.S. Drug Enforcement Administration fact sheets, unless otherwise noted. The list of drugs was compiled based on what drugs were discussed in a recent “Monitoring the Future” national study by the University of Michigan in Ann Arbor, which records teen drug trends.

An amphetamine prescribed to treat Attention Deficit Hyperactivity Disorder, or ADHD. Amphetamines can look like pills or powder and can cause high blood pressure, hallucinations and other symptoms similar to those of cocaine.

Cocaine powder

Also known as “coke” or “crack,” cocaine is typically distributed as a white powder. This highly addictive drug is snorted or injected after it has been dissolved in water. The drug has a “euphoric” effect on the user and causes excitation, anxiety and irritability. Cocaine is derived from coca leaves grown in South America.


Crack, or “cocaine base,” looks like white chunks or “rocks.” It is smoked and has the same effects on the body as cocaine powder. (See “cocaine powder,” above, for more information on effects and origin.)


Ecstasy, or MDMA, is a stimulant and psychedelic drug that is seen in the forms of tablets that look like candies, capsules, powder and liquid. Also known by the names of “disco biscuit,” “E” or “lover’s speed,” this drug alters the user’s perception, promotes euphoria and sexuality, and causes an “energizing effect.” MDMA is a synthetic chemical created primarily in Canadian labs and smuggled into the United States.


GHB, or Gamma-Hydroxybutyric acid, is also generic sodium oxybate. GHB comes as a clear liquid or white powder substance in small bottles. Users typically put it in drinks such as water or alcohol, making it one of the so-called “date-rape drugs.” The drug depresses the central nervous system, causing euphoria, confusion and memory impairment. GHB is produced in secret labs.


Inhalants, or “huff,” are chemical vapors found in household products such as glue, cleaning products, spray paint, felt-tip markers and cooking spray. Users breathe the chemicals in through their nose or mouth to feel a buzz similar to the effect of alcohol, including slurred speech, dizziness and euphoria. Users may inhale through bags, rags or balloons. Abuse can cause damage to the brain, such as impairment or dementia.


This “dissociative anesthetic” is a “club drug” that causes its users to “feel disconnected,” the DEA says. Other names for ketamine include “jet,” “cat tranquilizer” and “Special K.” It is a clear liquid or white powder distributed in small bottles, capsules or small bags. A user’s perception of surroundings and their sight and sound are often distorted. The drug can cause hallucinations, amnesia and sedation. Ketamine has been around since the 1970s, when it was used as an anesthetic for humans and animals, so it is often stolen from veterinary clinics.


Kreteks, according to the Centers for Disease Control and Prevention, are also known as clove cigarettes. The mixture of tobacco, cloves and additives are usually imported from Indonesia, the CDC notes. Kreteks, which are smoked, contain more nicotine, tar and carbon minoxide than regular tobacco cigarettes, and smoking kreteks can cause lung infection, the CDC adds.


LSC is a hallucinogenic drug taken orally. It is sold in the form of tablets, liquid and capsules, but it can also be used on absorbent blotter paper. Other names for LCD include “acid,” “dots” and “mellow yellow.” The drug causes high blood pressure and an increased heart rate, and triggers a “trip” similar to other hallucinogens such as PCP. LSD is produced in the United States in secret labs.


Marijuana is a psychoactive drug, meaning it is mind-altering. It is derived from the Cannabis sativa plant and is smoked as a joint cigarette or in a pipe or bong. Marijuana is a shredded mix of stems, seeds and leaves, contains more than 400 chemicals, and is usually a brownish-green color. Other names for marijuana include “blunts,” “dope,” “herb,” “pot,” “reefer” and “weed.” It is grown in North America, South America and Asia, both indoors and outdoors.


Also known as meth, methamphetamine is an addictive stimulant. It comes in pill or powder form, but crystal meth looks like bluish rocks. Meth can be used in a variety of ways. It is usually swallowed or snorted, but can also be injected or smoked. Meth stimulates the central nervous system and causes a rush when injected – but a long-lasting high when ingested or snorted. Methamphetamine is created in secret labs in the United States, but is mostly manufactured in Mexico.

OTC cough and cold medicines*

More than 120 over-the-counter cough and cold medications contain dextromethorphan, or DXM – a cough suppressor. Street names for cough and cold medicine include “Poor Man’s PCP,” “Robo,” and “Skittles.” When abused, it has a psychoactive effect, causing euphoria and hallucinations. DXM can also distort the senses, causing users to feel like they’re floating, for example. Depending on how large the dose, abuse of cough and cold medicines can have effects comparable to those of ecstasy, LSD or ketamine. These medicines can be purchased at pharmacies.


OxyContin, or Oxycodone, is a narcotic. The drug is usually taken orally, but the tablets are also crushed and sniffed, injected or mixed into drinks. Abusers of this drug experience euphoria, sedation and pain relief. Effects of this drug are said to be similar to codeine, heroin, meth and morphine. Oxycodone is partially made with thebaine from the poppy plant.


PCP – also called “angel dust,” “killer weed” and “supergrass” – causes hallucinogenic effects when smoked, ingested, snorted or injected. Abusers of the drug may experience hallucinations, anxiety, paranoia and severe mood swings. PCP is usually produced in secret labs within the United States.


Provigil, or modafinil, is a drug used to treat narcolepsy, according to the U.S. National Library of Medicine. Modafinil is meant to be taken orally and can be habit-forming, the library notes. According to a WebMD article, “Provigil blocks dopamine transporters,” which “increases the amount of dopamine in the brain – the brain’s ‘reward’ mechanism.”


Ritalin is a methylphenidate stimulant and looks like amphetamines because it comes in pill form. According to the U.S. National Library of Medicine, Ritalin is used to treat Attention Deficit Hyperactivity Disorder (ADHD), and is also used to treat narcolepsy. Methylphenidate comes in tablet, capsule and liquid form and can be habit-forming, the library notes. Stimulants cause a “rush” sensation and allow the user to get a high. Stimulants are also known as “crank,” “R-ball,” “speed” or “uppers.”


Rohypnol, or flunitrazepam, is a depressant that targets the central nervous system and is known as a “date-rape drug.” It’s an olive green pill with blue specks. Rohynol, also known as “roofies,” “forget pill” or “roaches,” has a sedative hypnotic effect on users, causes amnesia, confusion and impaired judgment. Rohypnol has been used to debilitate victims of sexual assault. It is often crushed and dissolved in drinks, swallowed whole or snorted. Rohypnol is made in other countries, such as Mexico, and smuggled into the United States.


Salvia divinorum is a perennial herb that has hallucinogenic effects when chewed, smoked or vaporized. The herb – also called “Maria Pastora” or “Sally-D” – is a part of the mint family and is native to Oaxaca, Mexico, but can be grown indoors and outdoors. Salvia can cause hallucinations, uncontrollable laughter, fear and panic.


Also called barbiturates, sedatives depress the central nervous system. Barbiturates come in the form of pills or tablets and are typically swallowed. These sedatives – also called “barbs,” “block busters,” “goof balls” and “red devils” – cause euphoria, relief from anxiety, irritability, paranoia, sleepiness and lack of inhibition.


Steroids are synthetic variants of the male hormone testosterone, and are often used to enhance muscles, physical performance and appearance. Steroids – also known by the names “juice,” “Arnolds” and “roids” – are available in a variety of forms, such as tablets, gels, creams, injectable solutions and patches. They are usually injected or ingested. Steroids cause dramatic mood swings, impaired judgment and aggression. Abusers who stop taking steroids often experience depression. Abuse can cause physical changes in men, including shrinkage of testicles and sterility, whereas women can develop a deep voice, increased facial hair and male pattern baldness. Steroids may be prescribed, but they are usually smuggled into the United States or ordered on the Internet.

Synthetic marijuana (K2)

Also known as K2 or “spice,” synthetic marijuana is a mixture of herbs sprayed with chemicals. Synthetic marijuana looks like potpourri and comes packaged in small, shiny bags. Users of synthetic marijuana abuse it by smoking it or drinking it in tea. The psychological effects are similar to those of marijuana (see “marijuana” for effects). The synthetic drug has been banned in many states – including Michigan as of June 2012. However, the drug, which was sold at some tobacco shops and gas stations, can still be found on the Internet. It is not certain where K2 is manufactured.


(See “sedatives,” above.)


This narcotic is a prescribed opioid, and is a combination of hydrocodone and acetaminophen. Hydrocodone usually comes in tablet or capsule form and causes euphoria, sedation and alters pain perception. Vicodin is sometimes referred to as “Vikes.”

  • I found a pill and I am curious if anyone can recognize what it is. The pill is a clear capsule with clear liquid and it has a smaller green pill inside. No markings are on the pill so I am unable to search it online.

      I would suggest asking a pharmacist to look at it or possibly contacting one a local lab to test it. You could reach out to this place in Ann Arbor, too, to see if they can test the pill: http://www.avomeen.com
