Second and Thirdhand Smoke Exposure, Attitudes and Protective Practices: Results from a Survey of Hispanic Residents in Multi-unit Housing.

Secondhand and third hand smoke (SHS, THS) exposure is prevalent in multi-unit housing (MUH). Minorities and low-income MUH residents are disproportionally exposed to SHS and THS compared to other populations. This study describes the characteristics, attitudes, knowledge, and behaviors related to SHS, THS and marijuana smoke exposure (MSHS) of a sample of Hispanic tenants in randomly selected MUH units in eastern metro Los Angeles (n = 402). Although most participants (97%) banned smoking inside their homes, 80% reported infiltration of SHS inside their apartments within the last year. Most (85%) favored a complete ban on smoking in apartment buildings. Twenty-eight percent did not know that marijuana (MSHS) smoke exposure is also harmful to their health. Knowledge scores were higher among Spanish-speakers (p < 0.05). Given the interpersonal barriers to advocating for change, widespread policy and communication interventions are also necessary to protect Hispanic MUH residents' rights to clean air in their living space.
