Yes. But once the child was old enough to get out on his own. I would not have control. Worst case scenario, he get's a snickers. That's not all too bad. Change that worst case scenario to, he gets all the booze he wants, that's not acceptable.
As far as I know, there are only 2 things that an 18 year old can not do and that is buy alcohol and buy a handgun. All other privileges and responsibilities of adulthood are bestowed on them at 18.
