Swapping marijuana for cannabis doesn't skew survey data

This study examined whether changing survey language from "marijuana" to "cannabis" affects how adolescents and young adults report their drug use. Researchers tested whether this terminology shift—driven by evolving cannabis policy and scientific language—would disrupt data consistency and reliability in prevalence surveys. The findings are reassuring for public health officials: switching the terminology had minimal impact on survey reliability, meaning researchers can use "cannabis" without significantly altering respondent behavior or creating discontinuities in long-term trend data.

The research addresses a practical challenge faced by epidemiologists and policymakers who rely on consistent survey data to track drug use patterns over time. When survey language changes, it risks confusing respondents or triggering different psychological responses that could skew results. However, this study demonstrates that adolescents and young adults interpret "cannabis" and "marijuana" similarly enough that replacing one term with the other doesn't materially affect how they report their substance use. This finding has important implications for maintaining the integrity of national surveillance systems like SAMHSA's National Survey on Drug Use and Health (NSDUH).

The practical significance is clear: public health agencies can adopt the more scientifically accurate and policy-aligned term "cannabis" while maintaining continuity with historical prevalence data. This supports informed drug policy decisions and allows researchers to track generational patterns in cannabis use without worrying that terminology changes introduce artificial fluctuations in reported usage rates.
