sure, marijuana shouldn't be considered 100% harmless, but it's ludicrous to argue it does the same amount of damage to people's bodies as ketamine (abuse can lead to kidney failure, bladder cystectomy) or even some sched. IV substances such as alprazolam (seizures from withdrawal can be fatal).
As someone who has taken ketamine for medical purposes and marijuana for not, it is utterly off-the-charts bonkers that they are classified identically.
A large dose of ketamine literally disconnects yourself from reality. Weed makes you tired.
Benzo addiction is very dangerous. Withdrawal can lead to life threatening or altering outcomes. I have a hard time understanding what property the scheduling is based on
