Legal highs.
Go to a local hardware shop and buy a bottle of asetone. Pour to old sock, put sock in plastic bag, inhale, tell every one how good friends they are then vomit. Or how about inhaling butane from lighters. You can buy them from night clubs. YAY! They are free and LEGAL! How about NOS? I have in my car! A whole pressurised bottle full! Inhale that! YAY!
Cough medizine! It's free! It's medizine! It's legal! You can can if from pharmacy, YAY, with out a receta from a doctor! Drink half of bottle, tell everyone how weird you feel, try not to sleep, dance like a ****ing idiot, try not to sleep, dance some more, sleep, drink some more medicine, tell everybody how sleepy you are, try not to sleep, dance like a ****ing idiot, try not to sleep, have sex with a man who looks like bratt pitt, sleep, wake up, feel good about yourself. Repeat!
