Objective:

To examine potential compensatory smoking in randomized clinical trials (RCTs) involving very low nicotine content cigarettes (VLNCs) and estimate the proportion of participants likely to compensate under a low-nicotine product standard.

Approach:
  • Systematic Review: Conducted a systematic review of literature focusing on RCTs that compared VLNCs with normal nicotine content cigarettes (NNCs) for at least 3 weeks.
  • Meta-Analysis: Performed a pooled meta-analysis of selected RCTs to estimate the extent of compensation among participants smoking VLNCs.
Key Findings:
  • Reductions in smoking, cigarette dependence, and toxicant exposure were consistently observed across trials.
  • Concerns about compensatory smoking similar to that seen with 'light' cigarettes were raised by stakeholders.
  • The study aimed to control for confounding by focusing on differences between VLNC and NNC conditions.
Interpretation:

Limitations:
  • Excluded RCTs with low-nicotine yield cigarettes and those with gradual nicotine reduction.
  • Data from some trials were unavailable, and implausible values were excluded from analysis.
Conclusion:
