Did you forget you have to be 21 to drink? And your wondering if this is legal?
Its a law, no drinking under the age of 21.
OF COURSE ITS ILLEGAL!
#1: your under age
#2 you were not at your own home with your own parents
#3 I kid your age had to lead police to find you, so that show me no adults were present to take the wrap for contributing to minors.
The ONLY way a kid 18 years of age can drink in the state of Ohio is when their parents give consent and are present, and even then if the police are called and you are drunk, your getting a fine.
Sorry.
I feel badly that no one taught you the rules, its clearly not your fault if you were not taught that under age drinking was against the law.
Smoking is illegal before 18 too.
And weed is illegal in Ohio, so is any other narcotic.
What might help you now is to go and look up the listing of Ohio intoxicant rules, I'm sorry your parents didn't teach you this ahead of time, and if they did, sorry bro, you got what you knew was coming.
Its not a big deal, every body and his brother has a DUI or a drunk and disorderly now a days, its just accidents and stupidity, when you get older make sure you keep your kids from making the same mistake.
