Enter your average cigarettes per day and whether your first cigarette is usually within about 30 minutes of waking. The tool suggests a common OTC 24-hour patch starting strength (often 21 mg or 14 mg on U.S. cartons) and an illustrative step-down sequence. It does not replace product labeling, quitlines, or clinician plans.

Mirrors the common consumer split: heavier daily smoking usually maps to the highest labeled starting patch; lighter daily smoking often maps to the middle strength.
For people near the cutoff, early-morning smoking can justify the higher starting tier in many teaching algorithms—still individualized in real care.
Step-down timing differs by brand and country; we show a generic educational sequence only.
At 8 cigarettes per day, first cigarette after 30 minutes of waking often maps to 14 mg (Step 2). The same 8 cigarettes with first cigarette within 30 minutes maps to 21 mg (Step 1) in this model—showing how the morning question can change the tier near the cutoff.
Over-the-counter nicotine patch cartons in the United States commonly organize three strengths (for example 21 → 14 → 7 mg per 24 hours) as Step 1 through Step 3. Labeling and exact thresholds vary slightly by manufacturer, but many use more than about ten cigarettes per day as a cue for the highest starting patch.
