According to the United Nations Office on Drugs and Crime, more than 29 million people suffer from drug addiction globally. Some of the most commonly abused prescription medications include opioids, amphetamines, and depressants. Central nervous system (CNS) depressants are medications that slow down activity in the human brain. These medications are sedatives, tranquilizers, and hypnotics that are prescribed to treat panic disorder, anxiety, stress, and sleep problems. The best-known CNS depressants are benzodiazepines, non-benzodiazepine sedative-hypnotics, and barbiturates.
When misused, depressant drugs can lead to tolerance with progressively larger doses needed to achieve the desired effect. After prolonged use, abrupt reduction in the dose of the medicine can cause withdrawal symptoms. Sudden cessation of depressant medications can have life-threatening consequences, including slowed breathing and seizures.
In severe cases, misuse of CNS depressants can lead to addiction with associated health problems and other negative consequences. People with an addiction to these medications need to undergo supervised detoxification with a gradual reduction in dose, followed by inpatient or outpatient counseling and behavioral therapies. Learn about the examples of depressants, how they affect the human brain and the signs and symptoms of addiction to these medicines.

What Are Prescription CNS Depressant Medications?
Central nervous system depressant medicines are sedative-hypnotics that reduce (depress) the level of arousal in the brain. They are available in capsule, pill, and liquid form. Here is a list of depressants divided by drug class:
- Valium (diazepam) is prescribed for anxiety and muscle tension. Taking it without
prescription can lead to addiction. Valium abuse is common in veterans dealing
- Klonopin (clonazepam) or K-Pin is a powerful sedative that is a highly effective
treatment for anxiety. In 2011, more than 75,000 people were admitted to
emergency rooms for Klonopin-related complications.
- Xanax (alprazolam) is a powerful benzodiazepine that is abused for its sedative effect. A severe Xanax overdose can lead to coma and death.
- Halcion (triazolam) is a sedative-hypnotic that is used to treat insomnia, anxiety, and alcohol withdrawal symptoms. Dependence to this drug can develop in as little as two weeks.
- Ativan (lorazepam) is a potent and highly addictive sedative prescribed for anxiety
disorders and seizure disorders. This fast-acting drug is intended for short-term use because prolonged use can be habit-forming.
Non-Benzodiazepine Sedative Hypnotics
- Ambien (zolpidem) is a prescription sedative that can be habit-forming even when taken at the prescribed dose for prolonged periods of time.
- Sonata (zaleplon) is a prominent non-benzo sleep aid that helps users enjoy a restful
sleep. This is a fast-acting drug produces mild euphoria followed by hallucinations, blackouts, and memory loss.
- Lunesta (eszopiclone) is a non-benzo sedative-hypnotic that makes a person feel relaxed and mellow. People abuse this drug to enhance sleep, ease stress, or get high.
- Amytal (amobarbital) has been called a miracle drug and truth serum for its ability to
produce a trance-like state. It is a bitter, white, odorless powder that is soluble in water and alcohol.
- Luminal (phenobarbitone) is an anticonvulsant hypnotic that is used for seizure control. This drug is habit-forming and addicts often mix it with other substances such as alcohol.
- Mebaral (mephobarbital) produces dangerous side effects such as confusion,
hallucinations, irregular heartbeat, and blackouts when taken without medical supervision.
- Nembutal (pentobarbital) is a prescription barbiturate that is used to treat insomnia and seizures and as a general anesthetic for surgery. It is abused for its anti-anxiety and sleep-inducing properties.
Signs and Symptoms of Depressants Addiction
When used legitimately under medical supervision and by prescription, depressants are a relatively safe and effective treatment for anxiety, sleep disorders, and convulsions. However, misuse can lead to dependence, and in severe cases, addiction. Withdrawal symptoms occur if the medicine is stopped suddenly. With regular use, the body adjusts to the medication and larger and more frequent doses are needed to achieve the desired effect. Prescription depressant misuse is defined as:
- Taking someone else’s medication
- Taking the medication in a way other than prescribed
- Taking medicine at a dose other than prescribed
- Taking the drug recreationally
- Taking medicine to counteract the effect of a stimulant
- Mixing the medication with alcohol or other drugs
Street names of popular depressants abused are candy, downers, sleeping pills, and tranks for benzodiazepines. Barbiturates are called phennies, barbs, reds, red birds, yellows, yellow jackets, and tooies on the street. Sleeping pills are referred to as A-minus or zombie pills. GHB (gamma hydroxybutyrate) is a CNS depressant that is commonly known as a date rape drug, club drug, liquid X, ecstasy, mils, G, and fantasy.
What are the depressants abuse signs and symptoms? There are some telltale signs that a
friend or family member is misusing these medicines. The person may always look sedated or drowsy, talk slowly or slur their speech, be unable to concentrate, or have poor coordination. A
lowering of inhibitions and poor judgment, i.e., taking risks they would not normally take, are other symptoms to look out for. Physical signs of addiction to depressants include a slowed heart rate, reduced breathing rate, and low blood pressure.
Depressants Abuse: Facts and Figures
Prescription depressants are addictive, and abuse of these medicines is a worldwide problem.
In the United States alone, an estimated 15 million people are struggling with prescription drug abuse. More than 22,000 overdose deaths are reported in the country each year. A survey found that teenagers believe prescription drugs are safer than street drugs and rely on the medicine cabinet at home as a source.
A study by the National Institute of Drug Abuse called Monitoring the Future found that 7.5 percent of 12th graders and 6 percent of 10th graders have used tranquilizers at some point in the past. In 2015, more than 8,700 deaths were reported from benzodiazepine overdose (Valium and Xanax). It is evident that depressant abuse is a pressing problem in America and around the world. How do these medications act and what makes them so dangerous?
What Do Depressant Drugs Do to the Brain?
CNS depressants increase the activity of a chemical called gamma aminobutyric acid (GABA) in the brain. GABA is the primary inhibitory neurotransmitter in the human brain. This chemical reduces brain activity and causes a calming and drowsy effect. Medicines that increase GABA activity, therefore, produce effects such as:
- Hypnosis (sleep inducing)
- Anxiolysis (anxiety reducing)
- Muscle relaxation
- Anticonvulsant effect
Because of these effects, depressants are prescribed for anxiety, sleep problems, and convulsions. When someone first starts taking a prescription CNS depressant, they feel sleepy, uncoordinated, and confused with poor concentration, slurred speech, slow breathing, and low blood pressure. These effects of CNS depressants can lead to serious injuries and accidents.
Short- and Long-Term Effects of Depressant Use
Some of the short-term effects of depressants include:
- Slowed brain function
- Lowering of blood pressure, pulse rate, and breathing rate
- Confusion and poor concentration
- Slurred speech
- Dilated pupils
- Difficulty urinating
- Impaired memory, coordination, and judgment
- Paranoia and suicidal thoughts
Some of the long-term effects of CNS depressants include:
- Breathing difficulties
- Sleep problems
- Sexual dysfunction
- Panic and anxiety
Benzodiazepine Addiction: Symptoms and Treatment
Misuse of CNS depressants is defined as taking the medication without a prescription or taking it at a dose or in a way other than prescribed. Misuse can lead to substance use disorder and addiction. Long-term use, even with a prescription, can lead to tolerance, which means more frequent or larger doses are required to get the expected effect.
If someone with an addiction to benzodiazepines or other CNS depressants abruptly stops taking the medicine, they may experience withdrawal symptoms, which can occur within a few
hours of the last dose, and include:
- Hyperactive reflexes
- Increased heart rate, blood pressure, and temperature
It is dangerous to attempt to quit CNS depressants without medical supervision. Treatment for substance abuse must always be obtained at reputed drug rehab facilities offering outpatient and inpatient programs. Detoxification (withdrawal from the drug) involves gradual tapering of the dose. The length of treatment depends on the severity of the dependence and other coexisting mental health issues. Addiction treatment for CNS depressants needs to be individualized and should include counseling, behavioral therapies, and group support programs.
Barbiturate Overdose: Can It Kill You?
Some people use barbiturates to get high. There is a significant risk of accidental overdose in people who misuse barbiturates. This is because there is a small difference between a dose that produces a high and a potentially fatal overdose. Barbiturate overdose can lead to respiratory depression (slowed or stopped breathing). This causes less oxygen to reach the brain, which can lead to seizures, permanent brain damage, coma, and death. If someone has a suspected CNS depressant overdose, it is important to call 911 for immediate medical attention.
Benzodiazepines rarely lead to respiratory depression or death. However, the sedation caused by misuse of these medications can lead to memory impairment, confusion, and poor motor coordination. These symptoms may be associated with severe injuries and accidents. Some people take a combination of alcohol and benzos to counter the unpleasant side effects of other street drugs. Combined benzodiazepine and alcohol abuse is extremely dangerous because alcohol is also a depressant.
