Where i live if i want to go into a store and buy some vodka, i can go in and buy some vodka. Some care some dont care about my age.But when money is shown they cant resist xD.So getting drunk here isnt that hard.Plus getting cigarettes isnt that hard, pretty much easier then getting alchohol.I know that there is a rule of age 21 in america so i kinda feel bad.Now i know that you can get alchohol but i can get drunk in a bar if i wanted to, BTW im 16 xD.
Here in Singapore it's 18 and 18. But if you somehow get your hands on cigarettes when you're younger and get caught, the police will just warn you. If you're a repeat offender, I think they tell your parents. But I also think your parents can write you a consent form that says they know and are fine with you smoking/drinking
