Look at it this way.
You have a young girl who eats normally for the most part, but a few times a month she freaks, pigs out, then makes herself vomit.
Does she have bulimia?
My answer is yes, she does. Addiction doesn't equate to a number or a quantity. It's how the person acts and reacts to various substances. Going on a binge for a day or two? That tells me something right there.
Crack (and other hard drugs) are, imho, like playing Russian Roulette. You keep pulling the trigger on blanks but someday, it's going to hit home.
You keep imbibing in addictive substances and one day, you're going to spin out of control.
From having read this board, crack is pretty nasty and really gets you hooked fast and hard. I can't imagine how someone could do it recreationally, or . . . recreationally for very long.
Why is it acceptable for anyone to be using this at all? what reason could someone possibly have to justify this?
