Understanding Drug Classifications – Strongest to Weakest

Table of Contents

You may have heard a drug mentioned as a Schedule II or III and wonder what it meant. Drug classifications are important because it enables doctors and patients to understand their dangers against their benefits. It can be helpful to understand about the different types of drugs and their classifications when you are prescribed a medication.

Drug Classifications

The US Food and Drug Administration is responsible for determining the classification of any medications sold for medicinal purposes. This authority comes from the Federal Food, Drug, and Cosmetic Act, which was passed in 1938. The act helps determine which drugs are approved for specific purposes and what dangers may exist when taking those drugs.

The Act has been amended over the years as more drugs have been developed and new classifications recognized. The FDA oversees both prescription medications and over-the-counter drugs. Prescription medications can only be given out by a doctor’s order. OTC drugs can be purchased in a pharmacy or other retail store and include medications, such as Tylenol or Motrin¹.

How are Drugs Classified

Various systems exist to classify drugs. They may be classified based on the active ingredients, how they act, or their use. For instance, an antidepressant may be classified by how it acts, such as which neurotransmitter it acts on. It can also be classified as treating anxiety or personality disorders, which may put it in multiple categories.

One system is known as the International Drug Evaluation and Classification Program. This organization is made up of professionals in law enforcement. Seven categories are used, which are based on the major effects on behavior from the drugs. These drug classifications include the following:

  • Central nervous system depressants: These drugs slow down the systems in the body, such as reduced heart rate or lowered blood pressure. Some drugs you will find in this category include Valium, Xanax, and Prozac.
  • Stimulants: Stimulants do the opposite of depressants because they increase systems, such as raising blood pressure, increasing heart rate and breathing. The drugs can increase the person’s energy as well. Drugs labeled as stimulants include Adderall and Ritalin.
  • Hallucinogenic drugs: These drugs are often prescribed to help one sleep. They can alter the perception of reality and may include Ambien, LSD, and ecstasy.
  • Dissociative anesthetic drugs: These drugs help the person to not feel pain, but they also distort their perception of reality and alter what they hear and see. Examples include PCP and special K.
  • Narcotic analgesic medications: This type of drug is also used to treat pain and is labeled as opioids. Examples include Vicodin, codeine, Demerol, and heroin.
  • Inhalants: These drugs are not usually sold as medication but alter a person’s perception of reality. Some examples of this substance include paint thinner, gasoline, and paint.
  • Cannabis products: Products in this category all contain THC and includes marijuana and hashish.

What are the Different Types of Drugs and Their Classifications?

Drugs are also labeled by Schedule for classification of substance abuse. This lets you know if they have any medical value and have a safe protocol for their use. Scheduling also provides information about whether they have a risk of being abused.

  • Schedule I: No recognized medical value and no protocol for safe use with a high potential for abuse. It includes heroin, many hallucinogenic drugs, some stimulants, and certain cannabis products.
  • Schedule II: Some medical value under certain conditions but a high potential abuse. Some examples include cocaine, amphetamines like Adderall, certain narcotics like morphine, barbiturates like Nembutal, and PCP.
  • Schedule III: These drugs have medical value with a somewhat lower risk than the first two schedules. They may include anabolic steroids, Tylenol with codeine, Mecoral, and testosterone.
  • Schedule IV: These drugs have accepted medical value and lower potential for abuse. They may include Benzodiazepines like Xanax, Tramadol, Sonata, Provigil, phenobarbital and chloral hydrate.
  • Schedule V: These drugs have a low risk for abuse and accepted medical use. They can include some cough medicines with codeine, anticonvulsant medications, and medications with a small amount of opium.

Drugs may be moved from one schedule to another based upon new evidence. This is quite common when new drugs are introduced, and it is determined that they are either more or less addictive than at first thought. However, the FDA has strict guidelines to follow when classifying drugs, which helps to ensure all drugs are labeled correctly².

Drugs in Schedules I, II, and III can be quite addictive. If you or a loved one are using any drugs that fit into one of these categories, you should be aware of the risks. If you become addicted or have a substance use disorder, you can get help.
