Narcotic is a term used to refer to certain drugs, including prescription medications that are controlled in the U.S., as well as illegal drugs sold on the streets. Narcotics are also called opioids. These drugs are grouped together because they affect the brain of the person taking it in a certain way. They are considered psychoactive in that they affect behavior and mood. Narcotic medications also share other characteristics with one another. The features of medicinal narcotics include pain relief and drowsiness. The word narcotic is derived from a Greek word that means stupor or sleep.

In the U.S. the term narcotic is often used incorrectly to describe any illegal drug. For example, cocaine may be called a narcotic, but in the technical sense it’s not. Based on governmental descriptions, narcotics include opium, semi-synthetic opioids, and synthetic opioids. Narcotics are specifically depressants or “downers.” Other drug classifications outside of narcotics include stimulants and hallucinogens.

Drug Schedules

The U.S. Drug Enforcement Agency outlines certain drug schedules. These aren’t just for narcotics but for multiple drug classes. There are five categories, also known as schedules that drugs are grouped into. These range from Schedule I to V.

Illegal Narcotics

Certain narcotics are illegal in the U.S. One example is heroin. Heroin is an opioid drug sold on the streets that is considered extremely addictive. Heroin can be smoked, snorted or most commonly, intravenously injected. It’s naturally derived and processed from morphine, which is found in poppy plants. These poppy plants are grown in Mexico, Southwest Asia, South America and Southeast Asia. Heroin is usually sold as a powder ranging in color from white to brown, and sometimes it comes in a black tar-like form.

Heroin is especially dangerous among drugs for several reasons. First, it acts very quickly on the person taking it, making it incredibly addictive. It also causes respiratory depression and frequently leads to fatal overdoses. Heroin is classified as a Schedule I substance in the U.S. Currently, heroin is the only Schedule I narcotic in the U.S., since it isn’t used for any medical purpose.

Narcotic Schedule

While heroin is the only drug considered an illegal narcotic, other prescription narcotics fall on different areas of the DEA’s list. The following are details of the narcotic schedule according to the DEA:

Some drugs do have an opioid component, and yet they are rated as less addictive than other scheduled narcotics. This is because these are often combination drugs and they tend to have an opioid component below a certain level.

If someone is caught with a substance that’s on the narcotic schedule and they don’t have a prescription, there are varying criminal penalties. Some of the factors that can determine criminal penalties for illegally possessing narcotics include how much of the drug they have, and whether or not they have a previous history of drug arrests.

Class A Narcotics

Other countries around the world also have drug schedules in place, although they’re labeled differently. One example is the UK’s Misuse of Drugs Act 1971. In the UK the drugs included on this list are called controlled drugs, much like the U.S. There are three categories under this law including Class A narcotics and drugs, Class B and Class C. Class A drugs are considered to be most dangerous, and they also have the most stringent legal consequences. Class C drugs are considered to have the lowest risk level. Class A narcotics in the UK include opioid prescription medications, as well as drugs like heroin.
