What This Study Found

Material deprivation, social deprivation, and household insecurity were positively associated with all three substances. Gentrified neighborhoods also had higher use. High immigrant/visible minority neighborhoods had lower use.

Key Numbers

All three deprivation measures positively associated with cannabis, cigarette, and e-cigarette use. Gentrified: higher odds. High immigrant/minority: lower odds.

How They Did This

Canadian Partnership for Tomorrow's Health cohort. Neighborhood-level measures linked via postal codes. Regression models adjusted for individual factors.

Why This Research Matters

Most prevention targets individuals, but neighborhood characteristics independently predict use, supporting environmental interventions.

The Bigger Picture

Gentrification increasing substance use challenges assumptions that neighborhood improvement automatically improves health.

What This Study Doesn't Tell Us

Cross-sectional. Self-reported. Postal code-level measures. Canadian context.

Questions This Raises

  • ?What connects gentrification to substance use?
  • ?Do immigrant neighborhoods provide protective structures?

Frequently Asked Questions

Why does gentrification increase substance use?

Possible mechanisms include displacement stress, disrupted social networks, and changing norms.

Why do immigrant neighborhoods have lower use?

Cultural norms, stronger community ties, and the "healthy immigrant effect" may contribute.
