Effectiveness of Different THR Products in Adult Population

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.
