Substance use is common among primary care patients and often goes undiagnosed. Although randomized studies of single-session interventions have not found the interventions to be effective in decreasing substance use among primary care patients, diagnosing substance abuse disorders is important in the evaluation of many common symptoms (eg, headache, anxiety) and abnormalities (eg, cardiac arrhythmias, renal insufficiency). It is also possible that referral of patients with substance abuse disorders to more intensive interventions will be helpful.
