Screening for Cannabis Use
Due to the high prevalence of cannabis use and significant risk of developing problem use, clinicians are encouraged to screen patients for cannabis use (e.g., “Are you using any cannabis or cannabis products such as marijuana, hemp, THC, or CBD?”). Affirmative answers should be followed up with questions about whether their cannabis use is causing problems.
The following screening tools can be used to help determine problematic cannabis use:
- CAGE Adapted to Include Drug Use (CAGE-AID) is a simple and multi-purpose screening tool for alcohol use and adapted to include drug use.9 CAGE-AID can be used to quickly determine if alcohol or other drug use, including cannabis, is problematic. Any “yes” response on CAGE-AID serves as a positive screen and should trigger an offer for substance use disorder treatment. CAGE-AID screening questions are:
- Have you ever felt that you ought to Cut down on your drinking or drug use?
- Have people Annoyed you by criticizing your drinking or drug use?
- Have you ever felt bad or Guilty about your drinking or drug use?
- Have you ever had a drink or used drugs first thing in the morning (Eye-opener) to steady your nerves or get rid of a hangover?
- The Cannabis Use Problems Identification Test (CUPIT) is an 8 to 10 minute screening tool specific to cannabis. CUPIT can be self-administered by patients prior to appointments and provides information on frequency and intensity of cannabis use in the past 12 months, cannabis use in the past 3 months, cannabis-induced problems, and risk of harm and dependence currently and in the past 12 months.10
