I know you can use lemon juice or vinegar to break the crack down,but a retarded friend of mine tried to use Balsamic Vinnagrette to break it down. What kind of infection or reaction does she need to watch out for?
Just crush it and dissolve it in water like you would do powder. Slamming crack though is going to really hurt your head and if it's cut with too much baking soda it will give you a nasty abscess.
