Benzodiazepines (BZO): Valium (diazepam)
Benzodiazepines are a large class of drugs used primarily for sedation and anxiety relief. Examples of Benzodiazepines include diazepam (Valium), chlordiazepoxide (Librium), alprazolam (Xanax), and clonazepam (Klonopin). Most benzodiazepine use in the US is due to prescription use, but some benzodiazepines are diverted for illegal consumption. Outside the US, particularly in Europe, benzodiazepines are more widely abused.
