Smokeless Tobacco Cessation Recommendations
Combining behavioral counseling with pharmacotherapy—specifically varenicline or nicotine replacement therapy (NRT)—is the most effective approach for quitting smokeless tobacco, with varenicline showing the strongest evidence for cessation success.
Pharmacotherapy Options
First-Line Medications
Varenicline is the preferred pharmacotherapy for smokeless tobacco cessation, with moderate-certainty evidence showing a 35% increase in quit rates compared to placebo (RR 1.35,95% CI 1.08 to 1.68) 1. This represents the highest efficacy among available medications for smokeless tobacco specifically.
Standard varenicline dosing: Start at 0.5 mg once daily for days 1-3, increase to 0.5 mg twice daily for days 4-7, then 1 mg twice daily from day 8 onward, initiated 1-2 weeks before the quit date 2, 3.
NRT may help people quit smokeless tobacco, with low-certainty evidence showing an 18% increase in quit rates compared to placebo (RR 1.18,95% CI 1.05 to 1.33) 1. While less robust than varenicline evidence, NRT remains a reasonable alternative.
Combination NRT is more effective than single-form NRT for tobacco cessation generally, using a 21 mg nicotine patch daily plus short-acting NRT (gum, lozenge, inhaler, or nasal spray) as needed for breakthrough cravings 4, 2.
Bupropion SR lacks evidence for smokeless tobacco cessation specifically, with low-certainty evidence showing no benefit (RR 0.89,95% CI 0.54 to 1.44) 1. While effective for cigarette smoking cessation 4, it should not be prioritized for smokeless tobacco users.
Important Pharmacotherapy Considerations
Treatment duration should be at least 12 weeks, with possible extension to 6 months-1 year to promote continued cessation 3.
Varenicline contraindications include brain metastases due to seizure risk, with common side effects including nausea 3.
Follow-up within 2-3 weeks of starting pharmacotherapy is essential to assess efficacy and manage side effects 2, 3.
Behavioral Interventions
Counseling Approaches
Cessation counseling significantly increases quit rates, with moderate-certainty evidence showing a 76% increase compared to minimal support (RR 1.76,95% CI 1.44 to 2.16) 1. This represents the strongest behavioral intervention effect.
Provide at least 4 in-person counseling sessions, with cessation rates plateating after approximately 90 minutes of total contact time 4, 2.
Brief advice (less than 10 minutes) is effective when more intensive counseling is not feasible, with moderate-certainty evidence showing a 24% increase in quit rates compared to no support (RR 1.24,95% CI 1.03 to 1.48) 1.
Counseling Content
Include practical problem-solving skills training to help users recognize high-risk situations for tobacco use and develop coping strategies 4.
Incorporate social support and motivational interviewing techniques to enhance engagement and readiness to change 4, 2.
Telephone counseling is effective when at least 3 calls are provided, and can be delivered by trained health care providers or professional counselors 4.
Combined Approach: The Gold Standard
Combining pharmacotherapy with behavioral counseling is more effective than either alone, with high-quality evidence showing an 83% increase in cessation rates compared to usual care (RR 1.83,95% CI 1.68 to 1.98) 4.
Combination therapy increases absolute quit rates from approximately 8% to 14-15% compared to usual care or brief advice 4, 2, 5.
The addition of behavioral support to pharmacotherapy modestly increases success, raising cessation rates from approximately 18% with medication alone to 21% with combined treatment 4.
Clinical Implementation Algorithm
Step 1: Assessment
- Screen for smokeless tobacco use at every health care visit to identify users who may benefit from cessation interventions 4.
Step 2: Advise and Assess Readiness
- Advise all smokeless tobacco users to quit at every visit 4.
- Assess readiness to quit and tailor intervention intensity accordingly 4.
Step 3: Initiate Treatment
- Start with varenicline plus behavioral counseling as the preferred first-line approach for motivated users 1.
- Alternative: Use combination NRT (patch plus short-acting form) plus counseling if varenicline is contraindicated or not tolerated 4, 1.
- For users not ready for intensive intervention: Provide brief advice and consider motivational interviewing 4, 1.
Step 4: Follow-up and Adjustment
- Schedule follow-up within 2-3 weeks to assess medication tolerance and provide ongoing behavioral support 2, 3.
- If initial therapy fails, switch to the alternative primary therapy (varenicline to combination NRT or vice versa) before considering second-line options 3.
Critical Caveats
Most smokeless tobacco cessation research comes from North America, with limited data from South and Southeast Asia where the majority of smokeless tobacco users reside 1. Evidence may not fully generalize to all smokeless tobacco product types.
Observational studies on smokeless tobacco and cardiovascular risk show mixed results, but increased coronary heart disease risk may occur, albeit less than with cigarette smoking 4.
Pharmacotherapy should always be combined with behavioral support for optimal outcomes, as the combination is more effective than either approach alone 4, 3, 6.
Healthcare setting recruitment shows stronger effects (RR 1.97) compared to community-based recruitment (RR 1.53), suggesting that clinical integration of cessation services enhances effectiveness 6.
