Social network norms predicted cannabis use frequency in young adults

Young adults whose social networks included more cannabis users tended to use more frequently, with this effect being stronger for recreational users than medicinal users.

What This Study Found

Descriptive norms (how much one's social contacts use cannabis) were associated with more frequent cannabis use (aIRR 1.19), but not with problematic use. The effect was stronger for recreationally oriented users (aIRR 1.62) than medicinally oriented users (aIRR 1.22).

Key Numbers

339 participants (182 medical patients, 157 nonpatients). Descriptive norms associated with use frequency (aIRR 1.19). Recreational users: aIRR 1.62. Medicinal users: aIRR 1.22. No association with problematic use.

How They Did This

Cross-sectional survey of 339 young adult cannabis users (182 medical patients, 157 nonpatients) in Los Angeles (2015-2016). Regression models examined associations between egocentric network characteristics and past-90-day cannabis use.

Why This Research Matters

Understanding how social environments influence cannabis use patterns can inform prevention and harm reduction strategies for young adults.

The Bigger Picture

The finding that social norms influenced frequency but not problematic use suggests that being around other users increases consumption but does not necessarily lead to dependency or problems.

What This Study Doesn't Tell Us

Cross-sectional design limits causal claims. Los Angeles sample may not generalize. Self-reported cannabis use and network composition.

Questions This Raises

  • ?Do medicinal users self-regulate against social pressure?
  • ?Would interventions targeting social norms reduce cannabis consumption among recreational users?

Frequently Asked Questions

Did peer cannabis use lead to problematic use?

No. While being around more cannabis users was linked to higher frequency of use, it was not associated with problematic or disordered cannabis use.

Why were recreational users more influenced by peers?

Medicinal users may have more structured, self-regulated use patterns driven by symptom management, making them less responsive to social pressure to use.
