Schedule 3 is a lower standard for researchers and prescribers but it does not fundamentally change the legal status of recreational, self-elected use. Other class 3 drugs include e.g., ketamine, a weird amphetamine (benzphetamine), and some drugs with the opioid codeine. None of these are legalized for recreational use. And my impression is that sentencing guidelines for marijuana just specify it by name rather than relying on its former schedule 1 status. It's a move in the right direction, but only barely.
