Living Near Cannabis Shops May Affect Use Intentions Differently by Race

Among 604 young adults in Los Angeles, living near more cannabis outlets was not associated with use intentions overall, but racial/ethnic subgroup analyses revealed that White young adults living near more recreational retailers had stronger intentions to co-use cannabis with tobacco.

What This Study Found

While outlet density showed no overall association with use intentions, stratified analyses revealed that White young adults near more recreational retailers had stronger co-use intentions, while Hispanic young adults near more medical dispensaries had lower e-cigarette use intentions.

Key Numbers

604 young adults; mean age 20.9; Los Angeles County post-legalization; density within 5 miles measured; no overall significant association; White young adults: more RCRs associated with stronger co-use intentions; Hispanic young adults: more MCDs associated with lower e-cigarette intentions.

How They Did This

Cross-sectional survey of 604 young adults aged 18-23 in Los Angeles County (2018), with outlet density measured as number of medical dispensaries, recreational retailers, and all outlets within 5 miles of respondents' homes.

Why This Research Matters

The finding that cannabis outlet density affects use intentions differently across racial/ethnic groups suggests that one-size-fits-all prevention strategies may miss important subgroup-specific risks.

The Bigger Picture

As cannabis retail environments expand, understanding how proximity to different types of outlets affects different communities can inform equitable zoning and prevention policies.

What This Study Doesn't Tell Us

Cross-sectional design; self-reported intentions may not predict actual behavior; limited to one metropolitan area; racial/ethnic categories are broad.

Questions This Raises

  • ?Do these intention differences translate to actual use differences?
  • ?Would limiting outlet density in certain neighborhoods reduce cannabis initiation among young adults?

Frequently Asked Questions

Does living near a cannabis shop make you more likely to use?

In this study, overall outlet density was not significantly associated with use intentions. However, subgroup analyses showed that White young adults near more recreational retailers had stronger intentions to co-use cannabis with tobacco.

Did all racial groups respond the same way?

No. The associations differed by race/ethnicity. Notably, Hispanic young adults near more medical dispensaries actually had lower intentions to use e-cigarettes, suggesting complex and community-specific dynamics.
