Imagine if the Devil could choose one thing to destroy Humanity, and have Humanity choose to do it repeatedly for hours and days and weeks and years on end, until there was nothing left....That is Crack. Once an addict inhales the first puff, that person will not stop smoking it constantly until he/she either runs out of money, or physically cannot stay awake any longer. That is the cold hard truth about Crack. When actively using, or waiting to use, in the throes of addiction, the addict doesn't care about anything else..not family, obligations, bank accounts, health, nothing. Imagine pure evil as a substance....it would look exactly like little white pieces of rock...
