would you report an under age drinker?

definitely.. while she can do what she wants, she has to learn that there ARE consequences. sounds like she isn't mature enough yet to partake in something that is so dangerous, even for adults.

yes

Do these men know how old she is? I'd try to find her help another way, maybe talk to her parents. She might know it was you..then again if the cops just happen to be checking IDs at the bar, she might not. If the bar does not know how old she is(some fake ids are good), I'd let them know. I was a bartender for a long time and have known bartenders who have been arrested simply for not being able to tell they were using a siblings id. ...But if they know or the owner knows, screw them. If not your putting the whole business through hell.

Absolutely! I had to do something similar once. When I graduated high school, I got a full time job and my own condo. 2 of my close friends were suppose to move in with me but backed out after we had already signed the lease. My boyfriend (now husband) said that his friends girlfriends were looking for a place. I didn't know them well but I agreed. They were horrible room mates. They would bring in people they barely knew. They refused to sign a new lease so my name was the only one on it. One night it got out of hand. I came home from work and found drinking, drugs, and some body that I have never meet before claiming that she had just kidnapped her child. I asked them to get out of my house and they refused. I called the cops and most of them were charged with underage drinking. It was only a $500 fine but they knew that I meant business.

Given the circumstances, yes. That girl needs help.
I wouldn't report all underage drinkers, but this one needs it before she destroys her life.

Yes.. she needs help. It isn't like she is going out once in awhile. She could end up killing herself. The fact that she is using sex to get alcohol and everything else means she is an alcoholic... maybe worse. Yes.. call... she'll never know who, and if somehow she guesses... i bet someday she will thank you.

Would I report an underage drinker? Not im most cases. Would I report her? Depends. I would probably start by giving her information for rehab, possibly form an intervention. If she gets FORCED to partake in a type of rehab (which is what will happen if legal matters are taken) then it is less likely to work. However, if information & intervention don't get through to her, instead of reporting her directly you could try tipping off that the bars she goes to are allowing underage drinkers. If the bar is faced with legal consequences they will be more strict with who they let in to save their own asses.

Where I live, 19 is the legal drinking age.

Which is why we always headed up to Canada for our 19th birthdays!!
