Screening and assessment of GHB use

Ask all new patients routinely and others (adolescents and adults) opportunistically and periodically about GHB use, as part of a general screen for disorders of substance use and gambling; these disorders are common (and often co-exist) and people are reluctant to disclose them, often due to fear of stigma. Screening and assessment of substance use and addictive behaviours outlines history-taking (including use of the ASSIST-Lite tool), examination, and investigations that should be considered in a broad review of substance use and addictive behaviour.
