The terms "Class A and B" are old terms. We used to label narcotics with letters. The letters were related to the strength or "power" of the narcotic. Class A was the strongest. The correct label these days is "Schedule 1 through 5 (some people include 6 for non-narcotic medicine). Schedule 1 is very strong narcotic, high abuse potential, and no medical value. Schedule 2 is strongest narcotic available for medical use. It has high potential for abuse. Schedule 3, 4, 5 are decreasing levels of narcotic power and abuse potential.
