Implication

Randomized trial reports a harm reduction protocol using e-cigarettes in oncology outpatients refusing standard cessation, indicating an alternative strategy to lower carcinogen exposure.

Key Points

  • To evaluate the effectiveness and implementation potential of providing e-cigarettes as a harm reduction strategy for cancer outpatients who decline standard tobacco cessation interventions.
  • Adult oncology smokers at an NCI-designated cancer center refusing standard tobacco treatment are randomized to receive either a 13-week supply of e-cigarettes with a switching workbook or a quit-smoking workbook alone (Trial registration: NCT07039292).
  • Participants randomized to e-cigarettes establish a switch date within two weeks to transition exclusively to e-cigarettes.
  • Assessments are administered biweekly during product provision, with primary follow-up extending through 6 months.
  • The primary endpoint evaluates complete switching at 6 months, defined as biochemically verified 7-day point prevalence abstinence with expired breath carbon monoxide ≤ 5 ppm.
  • Secondary outcomes assess implementation barriers and facilitators, changes in biomarkers of cancer risk, and health-related quality of life.
