I will set aside the technical aspect of nicotine.
On the economic front, we are talking about contraband and prices. If we draw a parallel with the legalization of marijuana, there is the whole issue with the price of the product. That's what makes contraband come into play or not. In this sense, it becomes advantageous for a regular smoker, who spends several thousand dollars a year anyway, to use contraband. If the price of cigarettes goes higher and higher, it is a damper for a certain segment of the population. However, for people who are regular consumers, it is advantageous to get contraband and encourage that market.
Have you noticed it in your studies and in terms of consumption?
