Since cannabis is well known to be mostly harmless, and much more harmless than alcohol, it seems like a good start. LSD might be in this category too. There are other ones that have value in medical, psychiatric and therapeutic settings, and definitely should not be completely banned simply because of their potential to cause harm. Another class offers zero benefit or unreasonably small benefit for the risks. "Bath salts" anyone? We have more socialism in the USA than many people realize and as long as I am paying taxes I'd prefer to not have to pay for unnecessary tragedies, second only to my wish to not fund the military and spies. We have to pay for quite a bit of emergency room care, social security death benefit, mental health or domestic violence counseling, etc. already due to the abuse of alcohol.
