1.     To change your mood
2.     To get high
3.     Because your friends are doing it
4.     In combination with other mind-altering  
        substances, particularly alcohol
5.     To cope with stress
6.     To escape
7.     In a party situation
8.     Alone, with potential help unavailable
9.     For the first time and you are unfamiliar
        with it
10.     At a dose higher than you are used to (or
        you don’t know how strong it is)
11.     When you have health issues that might
        affect your breathing or your ability to
        metabolize the drug
12.     And you don’t know about Naloxone (for
        opiates) and it’s not available anyway

The possibility that you may kill yourself is VERY high. Proceed at your own risk and do not blame the drug (you took it, it didn’t take you).

Relax – if you kill yourself, your parents will blame the drug, not you. And they will think about you every day for the rest of their lives.

Please also read my advice to your parents.
