A term used to describe powdered Caffeine, usually taken through insufflation. Favored by students for it's instant cocaine-like effect, combined with an increased feeling of readiness. It is important to note that while snow flour will give the rush and focus of coke, it lacks the euphoric feeling of it's counterpart.
