INTRODUCTION Tobacco excise taxation (hereafter tax/taxation) is effective for reducing tobacco consumption [1, 2]. Taxation impact is often assessed through price elasticity, a unitless measure that indicates the percentage change in consumption relative to a percentage increase in price. High-income countries (HICs) have a cigarette price elasticity of −0.4, meaning that a 10% price increase decreases consumption by 4% [3].

INTRODUCTION Randomized controlled trials (RCTs) are considered by many applied researchers as the gold standard for causal inference [1]. With a sufficiently large sample size, randomizing participants to treatment or control (placebo) conditions ensures that, in a probabilistic sense, all pre-treatment variables, measured or unmeasured, are similarly distributed across conditions up to the time of randomization. This theoretically allows the treatment effect to be isolated.
