Brief Summary
The study is a two-arm, parallel randomized controlled trial (RCT) with a treatment period of 12 weeks, and long-term follow-up at 52 weeks which plans to enroll 258 smokers from general adult population. Participants who meet the eligibility criteria and give their informed consent will be randomized (1:1) to one of two treatment arms: (1) E-cigarettes (18mg/ml) with individual counselling (2) Nicotine patches (21mg) with individual counselling. Eligible participants must be at least of legal age allowed for smoking in the country, of either gender, regular smokers (minimum 10 cigarettes/day for at least a year) and interested to stop smoking. Participants will be scheduled for a screening visit and a baseline (BL) visit at the trial site. The participants will be scheduled for eight study visits in total, including five treatment sessions and three follow-up visits, using both face to face interaction at trial site as well as follow up on telephone. Eight study visits are planned at weeks 1, 2, 4, 8, 12, 18, 24, and 52. Exhaled carbon monoxide assessment will be used at the trial site to quantify biochemically validated smoking abstinence. All secondary outcomes and self-reported usage of nicotine patches, EC and cigarettes will be monitored throughout the study.

Study Arms (2)
Study Arm A: Electronic Cigarettes (18mg/ml)
ACTIVE COMPARATORParticipants randomized to study arm A will be provided a free e-cigarette and sufficient nicotine cartridges (18 mg/ml) supply to last till next in person visit. Participants will be instructed to use the device ad libitum one week before their quit day to familiarize themselves with its operation and on their designated quit day will stop smoking tobacco cigarettes and instead use the e-cigarette exclusively for the next 12 weeks. Smokers often take 10 to 15 puffs over the course of 5 to 8 minutes, repeating this pattern with each cigarette. On the other hand, users of EC may periodically use it throughout the day, and they may or may not take their puffs like those of traditional cigarettes
Study Arm B: 21 mg nicotine patches
ACTIVE COMPARATORParticipants randomized to study arm B will be provided 21 mg nicotine patches supply to last till next in person visit. Participants will use the nicotine patch daily for one week before their quit day to familiarize themselves with its use. On their designated quit day they will stop smoking and use nicotine patches daily for the next 12 weeks. Usually a full-strength patch (15-22 mg of nicotine) daily for four weeks is suggested for use in majority of the smokers, followed by a lower strength patch (5-14 mg of nicotine) for an additional four weeks, depending on their body size and smoking habits
Interventions
E-cigarettes have been designed to resemble tobacco cigarettes. They include an aerosol generator, sensor, battery and storage area for liquid. They are either disposable or rechargeable. According to a study, e-cigarettes can deliver an average of 1.3 mg (range 0.4 to 2.6 mg) of nicotine from 15 puffs. Average Cmax after e-cigarette use is recorded as 8.4 ng/mL and Tmax achieved between 2 to 5 minutes
The nicotine patches are applied on the skin and nicotine is delivered at a steady rate. After administration, the peak blood levels are achieved within 6-10 hours. The levels remain constant, reducing by 25-40% with use of patches once daily. The patch is typically administered every 24 hours for no longer than 12 weeks. The dose of the patches is often determined by daily cigarette consumption and level of addiction.
