the number of tobacco user will decrease

Answer 2

High taxes means, consumption of tobacco reduces. If in a region where tobacco is exported from other countries, if taxes increases, the prices of tobacco will rise and it will be difficult for every citizen to buy it and use it which will reduce its consumption eventually.

High taxes, not just effect the consumer but also impact the buyer who export stuff from different countries.
