Introduction Many people remove the tobacco leaf from cigars and replace it with cannabis (ie, blunts), but few studies have examined whether messages about the risks of cigars, like warnings on cigar packages, can affect blunt use. Methods Participants were 438 U.S. adults who reported past 30-day cigar use and ever blunt use, recruited from a probability-based national panel to take an online survey. In a 2 × 2 experiment with a between-subjects design, we manipulated two cigar warning characteristics: (1) warning type: text-only versus pictorial (ie, text + image) and (2) warning size: 30% (smaller) versus 50% (larger) of the product package. Participants then viewed six different warnings on a fictious cigarillo package, within their randomly assigned condition. After evaluating all stimuli, participants were asked the extent to which the warnings discouraged them from wanting to use cigars to smoke cannabis (ie, blunt perceived warning effectiveness). Response options ranged from "not at all" (1) to "a great deal" (5). Results We observed no main effects of warning type or size on blunt perceived warning effectiveness. However, a significant interaction existed between the two experimental manipulations (p =.009). Whereas adding images made no difference to blunt perceived warning effectiveness when warnings were smaller (simple effect: −0.22, p =.28), images mattered for larger warnings. Specifically, adding images increased blunt perceived warning effectiveness when warnings were 50% of the product package (simple effect: 0.52, p =.008). Conclusions This experiment provides preliminary evidence that larger pictorial cigar warnings may discourage blunt use relative to larger but text-only warnings. Implications Blunts, which are hollowed out cigars with tobacco leaf wrappers that are filled with cannabis leaf, are one of the most common ways in which tobacco and cannabis are used simultaneously, yet few studies have examined whether messages about the risks of cigars can affect blunt use. We conducted an online experiment concerning the perceived effectiveness of cigar warnings among people who use blunts recruited from a probability-based panel. Results provide novel, preliminary evidence that larger pictorial cigar warnings may discourage blunt use, relative to larger but text-only warnings. More research evaluating cigar warnings on blunt use is needed. [ABSTRACT FROM AUTHOR]

Significance: Cigars are sometimes marketed with cannabis references because they are often used for smoking blunts (i.e., cannabis rolled in cigar paper with or without tobacco). However, little research exists on the impact of cannabis co-marketing on cigar perceptions., Methods: Participants included 506 US youth (ages 15-20) recruited April-June 2023 through Qualtrics who reported ever using little cigars or cigarillos (LCCs), past 30-day use of LCCs, or susceptibility to using LCCs. We then conducted a between-subjects experiment, randomizing youth to view one of two cigarillo packages: 1) a package with cannabis co-marketing (i.e., the package included a cannabis-related flavor descriptor and the word "blunt" appeared in the brand name and product label) or 2) a package with no cannabis co-marketing. We assessed the effects of the packaging on perceptions of product ingredients, addictiveness and harm perceptions, product appeal, susceptibility to using the product shown, and purchase intentions., Results: Packages with cannabis co-marketing were perceived as more likely to contain cannabis (OR: 5.56, 95 % CI: 3.73, 8.27) and less likely to contain tobacco (OR: 0.42, 95 % CI: 0.25, 0.70) or nicotine (OR: 0.57, 95 % CI: 0.40, 0.82). Cannabis co-marketing also led to higher susceptibility to using the product shown (B: 0.21, p = 0.02). We did not find evidence that cannabis co-marketing changed harm perceptions or purchase intentions., Conclusions: Among a sample of US youth, cannabis co-marketing on cigar packages may change perceptions of product ingredients and increase susceptibility to using such products, which could lead to the initiation of cigars and cannabis., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Introduction: Pictorial health warning labels (HWLs) can communicate the harms of tobacco product use, yet little research exists for cigars. We sought to identify the most effective types of images to pair with newly developed cigar HWLs., Aims and Methods: In September 2021, we conducted an online survey experiment with US adults who reported using little cigars, cigarillos, or large cigars in the past 30 days (n = 753). After developing nine statements about health effects of cigar use, we randomized participants to view one of three levels of harm visibility paired with each statement, either: (1) an image depicting internal harm not visible outside the body, (2) an image depicting external harm visible outside of the body, or (3) two images depicting both internal and external harm. After viewing each image, participants answered questions on perceived message effectiveness (PME), negative affect, and visual-verbal redundancy (VVR). We used linear mixed models to examine the effect of harm visibility on each outcome, controlling for warning statement., Results: Warnings with both and external harm depictions performed significantly better than the internal harm depictions across all outcomes, including PME (B = 0.21 and B = 0.17), negative affect (B = 0.26 and B = 0.25), and VVR (B = 0.24 and B = 0.17), respectively (all p < .001). Compared to both, the external depiction of harm did not significantly change PME or negative affect but did significantly lower VVR (B = -0.07, p = .01)., Conclusions: Future cigar pictorial HWLs may benefit from including images depicting both or external harm depictions. Future research should examine harm visibility's effect for other tobacco pictorial HWLs., Implications: The cigar health warning labels (HWLs) proposed by the US Food and Drug Administration are text-only. We conducted an online survey experiment among people who use cigars to examine the effectiveness of warnings with images depicting different levels of harm visibility. We found HWLs with images depicting both an internal and external depiction of cigar harm, or an external depiction of harm alone, performed better overall than images portraying internal depictions of harm. These findings provide important regulatory evidence regarding what type of images may increase warning effectiveness and offer a promising route for future cigar HWL development., (© The Author(s) 2024.
