We know that e-cigarettes with nicotine are less addictive than cigarettes because they don't deliver nicotine to the brain as quickly as a cigarette does through the smoke, and most devices don't deliver as much nicotine. They are less addictive than cigarettes, but yes, they definitely have addictive potential, which is why we think it's urgent that the government introduce measures to prevent non-smoking youth from getting their hands on these products, to the extent possible.
