Raising the legal smoking age to 21

To protect our young generation from the poisoning of smoke, I propose raising the legal age to buy and use tobacco products from 18 to 21.
Studies have showed that people who begin smoking at an early age are more likely to develop a severe addiction to nicotine than those who start at a later age. Tobacco industry is still targeting young adults in order to turn them into long term money-spinner.
For the sake of the health of our young generation, please show your support!
