Benzodiazepines, also known as "benzos," are a class of medications that slow down activity in the brain and nervous system. They are depressants that produce sedation and hypnosis, relieve anxiety and muscle spasms, and reduce seizures. Benzodiazepines work by telling the brain to release a neurotransmitter called gamma-aminobutyric acid (GABA), which makes the nervous system less active. They are usually prescribed to treat a variety of conditions, including anxiety, panic disorders, seizures, and sleep disorders.

Benzodiazepines are classified as controlled substances in many countries, including the US, which means that they require a prescription to obtain. It is illegal to have or obtain them without a prescription. Benzodiazepines can be addictive, and the risk of becoming emotionally and physically dependent on them increases the more they are taken. They should only be taken at the lowest dose for the shortest possible length of time.

Some common benzodiazepines include alprazolam, diazepam, lorazepam, and clonazepam. Street benzos are illicit drugs that are similar to prescription benzodiazepines but can be far more dangerous. They are unpredictable in content and potency and can cause hospitalization and death.
