Adolescence is the transitional stage from childhood to adulthood, usually the years between ages 13 and 19 which are characterized with rapid growth and puberty changes.
The statement that adolescence is universal is true. Adolescence is universal because all societies recognize adolescence as a stage of human development.
For me, I would directly go to the hospital to have my friend checked out. I would also call her parents to let them know what's happening. Since it is out of character for her to do drugs and drink alcohol, it is easy to conclude that someone drugged her drink.
It is better to have her admitted in the hospital than send her home because I don't know what drug was slipped in her. She might have an adverse reaction to the drug and alcohol in her system.
I would rather let my friend be safe than sorry and I know that her parents would be more concerned for her well-being than being late from going home.
