Stigma towards persons who use methamphetamine: Results from a nationally representative survey of U.S. Adults

This study seeks to understand the general adult population’s knowledge, attitudes, and stigma towards methamphetamine use and people with a history of methamphetamine use utilizing a cross-sectional national survey. We analyzed data from a cross-sectional survey drawn from AmeriSpeak®, a probability-based ongoing panel of over 35,000 households representative of the U.S. household population. We developed a 10-item social stigma scale, and estimated a multivariable generalized linear regression model for public stigma towards methamphetamine use as our dependent variable and a series of covariates. Six adjusted independent variables were noted to be significantly associated with higher stigma towards methamphetamine use: older age, higher household income, married status, Republican party affiliation, no history of methamphetamine use, and higher racism score. Sex assigned at birth, race (with Black as reference category), education level, and history of arrest or incarceration showed no statistical significance in stigma scores. In a separate regression model limited to people with a history of methamphetamine use (n = 727), notably White respondents had lower stigma compared to Black respondents. Our large population-based survey identified several factors associated with higher stigma towards those who use methamphetamines, including higher racist attitudes which was associated with a higher stigma score and higher internalized stigma amongst Black respondents with a history of methamphetamine use. Given the scope of methamphetamine use in the U.S., addressing stigma, in particular in regard to race, may impact the nation’s public health efforts to reduce methamphetamine-associated adverse outcomes.
