The study had some limitations as described by the authors, but it was null, just like prior studies in the ED and in primary care.2 3 Screening, brief intervention and referral to treatment (SBIRT in the USA), simply does not improve outcomes for unhealthy drug use.
Unhealthy substance use is not just one risk factor (eg, weekly cannabis use) or disease (eg, opioid use disorder) just as heart disease comprises many diseases all of which have specific treatments. A one-size-fits-all approach like SBIRT will not be effective; tailoring will be necessary.

Some will enter treatment or change regardless of our advice (eg, the control group in Merchant et al 1); they are aware of the risks and want help. A few will have (1) low or …
