Sipping slowly and alternating with water may not be enough. A new meta-analysis of 15 randomized controlled trials found that common "protective behavioral strategies" — like drinking slowly, using a designated driver, or alternating with water — have little to no meaningful impact on reducing heavy drinking or alcohol-related harms when used alone. They may offer modest benefits, but only as part of a broader intervention.
Popular harm-reduction strategies for heavy drinking fall short as standalone tools
A new meta-analysis published in Psychiatry Research analyzed 15 randomized controlled trials and found that so-called protective behavioral strategies (PBS) — including drinking slowly, using a designated driver, or limiting drink counts — have little to no meaningful effect on reducing alcohol consumption or alcohol-related harms when used as standalone tools.
The findings do leave a small door open: PBS were linked to modest reductions in drinking frequency, and showed slightly better results over longer follow-up periods or when paired with broader behavioral interventions. Experts note that a culture of heavy drinking and individual biological differences mean that more comprehensive, community-level approaches are likely needed.
By the Numbers
Why it matters: With excessive drinking tied to nearly 178,000 U.S. deaths per year, clinicians need effective tools. This study signals that brief, single-session PBS interventions aren't enough on their own — they work best as complementary components within broader motivational and behavioral programs.
