Brief Summary:
This is a 12-weeks, open label, non-inferiority trial comparing HTPs vs ECs in terms of efficacy, adoption rate and acceptability, tolerability, and tobacco harm reduction in 220 healthy smokers, not motivated to quit, randomized (1:1) to switch to one of these products. The duration of the study, from the enrollment to the study close out for all the patients at week 24 (follow-up), will be approximately 12 months. Enrollment period will last about 6 months with the support of a multi-channel advertising method. This will include location-based advertising on social networks, advertising in local media, information days organized within the city.

Arm Intervention/treatment
Experimental: IQOS
Device: IQOS

Active Comparator: E-CIG
Device: E-CIG

Primary Outcome Measures :
  1. Smoking Cessation [ Time Frame: 12 WEEK ]
    to compare the efficacy of HTP and EC, in terms of quit rates at week 12, by self-reporting abstinence from classic cigarette [validated by an Exhaled breath Carbon monoxide (eCO) measurement ≤10ppm)]

Secondary Outcome Measures :
  1. Smoking Reduction [ Time Frame: Week 12 ]
    To compare the smoking reduction derived from the use of HTP and EC, intended as a 50% reduction in the number of conventional cigarette/day at week 12, defined through self-reporting;

  2. Adoption rate [ Time Frame: Week 12 ]
    To compare the adoption rate to product use [by collecting (empty) refill bottles and used heathsticks on a daily basis, verified by a study diary filled daily by the subject];

  3. Acceptability [ Time Frame: Week 12 ]
    To compare the acceptability derived from the use of HTP and EC [by a validated self-report inventory]

  4. Number of participants with product-related adverse events [ Time Frame: Week 12 ]
    To compare number of participants with adverse events derived from the use of HTP and EC as assessed by CTCAE v4.0

  5. Tobacco Harm Reduction [ Time Frame: Week 12 ]
    changes in Biomarkers of Biological Effects (BoBE) such as: eCO in the exhaled breath (i.e. eCO), step test values

  6. Reliability [ Time Frame: Baseline visit, Week 12 ]
    To compare the reliability of HTP and EC, in terms of incidence and kind of malfunctioning events, through self-reporting.
