The US Drug Enforcement Administration classifies benzodiazepines as depressants which aim to reduce anxiety, help with sleep difficulties such as insomnia, and in some cases, prevent medical issues such as seizures. The drug delivers a calming and sometimes euphoric effect depending on the type and dose. But with the good the drug brings comes the negative consequences. Benzodiazepines are addictive substances that can cause forgetfulness, irritability, and even hostility in some users.
