Camel crush how does it work

The Camel Crush with the capsule crushed contained 5. The study was conducted at Roswell Park from December to February Once determined eligible for the study, a participant was randomly assigned to one of four sampling groups, which varied in the sequence of the cigarette products that were smoked Camel Crush crushed, Camel Crush uncrushed, Camel Menthol crushed, and Camel Menthol uncrushed Table 1.

At the baseline session, all participants smoked their preferred brand, which allowed them to serve as their own control. A total of five 2-hour laboratory sessions occurred over about two weeks with at least 24 hours between consecutive sessions.

Participants were asked not to smoke 45 minutes before coming to the laboratory to ensure that they were ready for a cigarette. At the start of each session, the participants completed the Questionnaire of Smoking Urges 8 and Minnesota Nicotine Withdrawal scale 9.

These measures were used to ensure that the craving for a cigarette, which could affect smoking behavior, did not differ between sessions.

At each session, two cigarettes of the product assigned for that session were smoked with a minute interval between cigarettes. Ten minutes after the last puff, exhaled CO levels were reassessed. This procedure was repeated for the cigarette replicate after 45 min. At the end of each session, the perceived risk of the cigarette product smoked at that session was assessed.

After smoking each cigarette provided during this study, the Cigarette Evaluation Scale and the Sensory Scale were used to assess the overall sensory attributes of each product 6 , 10 - The Cigarette Evaluation Scale evaluates items that can be broken down into the following subscales: satisfaction, psychological reward, aversion, and relief of craving 10 , 11 ; items were rated on a scale of 1 not at all to 7 extremely , and item scores for each subscale were averaged 10 , The Sensory Scale is a linear scale from 0 to 10 with descriptive anchors6.

Participants were asked to mark along the scale to indicate their rating for the following items: strength, harshness, heat, draw, taste, satisfaction, burn rate, mildness, aftertaste, staleness, and smoke harshness, strength and smell.

These items have been used by the tobacco industry and elsewhere 6 , Exhaled CO boosts were calculated by taking the difference between the pre- and post-smoking CO level for each cigarette smoked during this study. In addition, the smoking topography measures total smoke volume, average puff volume, puff duration, inter-puff interval, and puffs per cigarette were obtained from the CReSS device for each cigarette smoked during this study. At the end of each session, a rung risk ladder was used to assess perceived health risk of the cigarette product after smoking the cigarette replicates assigned for that session.

The top of the ladder represented a greater health risk and the bottom was no or little health risk Basic descriptive statistics and analysis of variance ANOVA were used to compare demographic and smoking behavior characteristics of study participants.

The sensory perception measures, CO boost, and smoking topography were measured for each cigarette administered. Differences were evaluated between the cigarette products and between the two cigarette replicates smoked at each session. Eighteen participants completed the study Figure 1. A prototypical participant was non-Hispanic White Most smoked Seneca brand mentholated cigarettes The Cigarette Evaluation subscales were compared between cigarette products as well as cigarette replicates.

No significant differences were seen for mean scores of the Cigarette Evaluation subscales between the cigarette replicates. In addition, no significant differences were seen between cigarette products for mean scores for the satisfaction, psychological, and aversion subscales. All of the sensory scale items mean scores were compared between cigarette products as well as cigarette replicates.

Three participants were excluded from the smoking topography analyses due to CReSS device equipment failures. There were no significant differences in any of the smoking topography measures between cigarette products or between the cigarette replicates Table 3. In addition, there were no significant differences in mean CO boosts between cigarette brand or between the cigarette replicates data not shown.

Summary of smoking topography measures a by cigarette product, — The risk perception of each cigarette product was assessed at the end of each session. Scores were averaged and compared across cigarette products. Scores showed that most participants felt that all cigarette products where harmful to their health. Smoking urges scores were lowest prior to the participants smoking their preferred brand PB: 3. However, there were no significant differences between cigarette products when looking at the post hoc test comparisons.

However, despite the various concentrations of menthol and various delivery methods of menthol, these established menthol smokers did not demonstrate differences in smoking behavior or CO boost for Camel Crush and Camel Menthol products, crushed or uncrushed.

These findings are consistent and build upon findings from a study by Strasser et al. However, this change in total puff volume did not translate to differences in biomarker levels. In the current study, total puff volumes for Camel Crush crushed and Camel Crush uncrushed were not significant.

Furthermore, the total puff volumes for use of the Camel Crush crushed and the Camel Crush uncrushed in the current study were comparable to the study by Strasser et al. However, the study by Strasser et al. The current study found differences in similar subjective ratings, including overall taste and aftertaste, but there were also significant differences associated with relief of craving e. This study is the first, to our knowledge, to examine two primary delivery methods of menthol available in the US menthol added to the tobacco and menthol in a crushable capsule in the filter and their effect on consumer sensory perceptions, perceived risk and appeal, and smoking behavior and biomarkers.

Although this study allowed for participants to serve as their own controls, which eliminates the potential for confounding by demographic and smoking behavior characteristics, there are some limitations to this study. This study included current smokers and did not assess the effect of menthol on smoking initiation. In addition, the participants showed low nicotine dependence and our findings may not be generalizable to all smokers of menthol products.

This study was designed as a pilot study with a limited sample size. The CReSS Topography device malfunctioned during some study sessions, and one participant was given the wrong cigarette product during one study session, which resulted in missing data for some subjects, further depleting our sample. In the future, the shelf-life of the filter capsule should be assessed to better understand any potential changes or degradation of the filter capsule that occurs over time and at various temperatures.

Furthermore, while tobacco control efforts have mitigated overall smoking rates in the US, the prevalence of menthol cigarette use is decreasing at a slower rate than that of non-menthol cigarettes 1 , Smokers experience menthol as a minty taste and aroma that also produces anesthetic effects in the airways, which reduces the harshness of the cigarette smoke and may contribute to the slower decline in the prevalence of menthol cigarette use 1 - 2.

Although the crushable filter capsule allows greater concentration of menthol to be transferred into the smoke and may limit migration and dissipation of the menthol flavor over time or after the pack is opened 5 , the delivery method and amount of menthol present did not seem to affect short-term smoking behavior, sensory perceptions, or perceived risk among a small sample of current, established adult menthol smokers in the present study. In addition, despite a non-mentholated condition among menthol smokers, participants did not seem to perceive differences in delivery method of menthol or perceived risk ratings.

It is possible that consumers of cigarette products may be attracted to the innovative technology of the crushable filter capsule as opposed to the taste experience, however, additional research is needed.

Open in a separate window. The FDA was forced to act by an April 29 court deadline to respond to a citizen's petition from seeking a ban on menthol cigarettes.
