Two behavioral treatments for smoking reduction: a pilot study

Area of Science:

• Behavioral Science
• Addiction Research
• Public Health

Background:

• Smoking cessation remains a significant public health challenge.
• Many smokers are interested in reducing, rather than quitting, their nicotine intake.
• Behavioral interventions are crucial for managing nicotine dependence.

Purpose of the Study:

• To compare the efficacy and acceptability of two behavioral treatments for smoking reduction.
• To evaluate the impact of increasing inter-cigarette interval versus selecting easy-to-eliminate cigarettes.
• To assess the effectiveness of these strategies when combined with nicotine gum.

Main Methods:

• A crossover design study with 20 US cigarette smokers interested in reduction.
• Participants engaged in two conditions: increasing inter-cigarette interval or cigarette selection, each for two weeks.
• Measurements included self-reported cigarettes per day, carbon monoxide, cotinine, thiocyanate, treatment acceptability, and adverse events.

Main Results:

• Both behavioral treatments significantly decreased self-reported cigarettes per day (45% and 38%) and carbon monoxide levels (20% and 19%).
• Increasing the inter-cigarette interval showed a slightly greater reduction in cigarettes per day compared to cigarette selection.
• No significant changes were observed in cotinine or thiocyanate levels, and both treatments were deemed acceptable and safe.

Conclusions:

• Both behavioral interventions are acceptable and efficacious for reducing smoking.
• These methods offer viable options for smokers not ready to quit entirely.
• Further research with larger sample sizes and longer follow-up periods is warranted.
