Class A drugs actually have a range of benefits, from curing addiction(!), depression, PTSD, migraines, and inspiring people creatively. This is not for all drugs, and some also have associated risks, but they are not by nature "bad".
Unfortunately, these drugs often are unpatentable, so it's safer to make them illegal (class A so that law says they "have no medical purpose"). Then big pharma can find less effective substances, sell them for more, and it's all under the guise of safety.
