Honesty is NOT a characteristic of crack use. It is a drug that quickly demands more and more. QUCIKLY. People stay up for as long as they can use it, which means cost can go up into the thousands of $$ per day. Writing bad checks is almost automatic and sales and prostitution are commonplace. The filler used in this stuff can also be anything you can get your hands on. Various types of acid to Mannitol to baking soda are common and any substance is possible. Even the pro's have problems treating crack, spice, ice and the like-Run don't walk away from ANYONE who is hooked to this stuff for your own good. YOU CAN NOT HELP. CAN NOT. The end.
