Using blunts during a cigarette quit attempt did not significantly reduce chances of quitting
Among 500 Black adults in a smoking cessation trial, those who used blunts (cannabis-tobacco wraps) had similar quit rates to non-blunt users at both 12 and 26 weeks, regardless of whether they received varenicline or placebo.
Quick Facts
What This Study Found
Of 500 participants, 75 (15%) reported blunt use during the study. Blunt users had similar odds of quitting at Week 12 (OR 0.68, 95% CI 0.31-1.5) and Week 26 (OR 0.84, 95% CI 0.38-1.87) as non-blunt users. There was no interaction between blunt use and varenicline treatment on cessation outcomes.
Key Numbers
500 participants (300 varenicline, 200 placebo); 75 (15%) used blunts; mean age 45.6; 42% female; quit odds at Week 12: OR 0.68 (95% CI 0.31-1.5); Week 26: OR 0.84 (95% CI 0.38-1.87); no treatment interaction
How They Did This
Secondary analysis of a double-blind, placebo-controlled RCT comparing varenicline (n = 300) to placebo (n = 200) for smoking cessation among Black adults. Blunt use was assessed at baseline and weeks 4, 8, 12, 16, and 26. Abstinence was verified by salivary cotinine.
Why This Research Matters
Blunt use has been a concern in cessation research because the nicotine in tobacco wraps could undermine quit attempts. This finding suggests blunt use may not be the barrier to quitting that clinicians feared.
The Bigger Picture
For Black adults who use blunts, this finding suggests they should not be excluded from or discouraged from cigarette cessation efforts. However, blunts still expose users to combusted tobacco products.
What This Study Doesn't Tell Us
Secondary analysis with relatively small blunt user subgroup (75); may be underpowered to detect meaningful differences; blunt use was not the primary study focus; cannot assess impact of blunt frequency or quantity; results specific to Black adults
Questions This Raises
- ?Would targeting all combustible products (including blunts) simultaneously improve overall cessation?
- ?Does blunt use change after cigarette cessation?

Evidence Hierarchy
Frequently Asked Questions
Did using blunts make it harder to quit cigarettes?
Not significantly. Participants who used blunts had similar quit rates at both 12 and 26 weeks compared to those who did not use blunts. The odds ratios (0.68 and 0.84) suggested a slight numeric disadvantage but did not reach statistical significance.
Did varenicline work differently for blunt users?
No. There was no interaction between blunt use and varenicline treatment, meaning the medication appeared to work similarly regardless of whether participants also used blunts during their quit attempt.
