There's supposedly a bill in the Senate to deschedule cannabis that would probably get some Republican support (Cory Gardner was holding up judicial nominees for months until he got assurances that the feds would honor Colorado's pot laws). Plus the newly approved CBD drug gives lie to the "no medical use" provision in Schedule I of the Controlled Substances Act (where it is currently).
Can't wait for the day it's legal. Two or three people a week are usually arrested for possession even in the lilywhite uber-rich town I grew up in. Whether you're the Alabama of provinces (though I guess that'd be the prairies?) or the most liberal, cannabis is/was still a financial bonanza for law enforcement.
If there's an upside to the Supreme Court going further right it's that generally the more conservative justices are more skeptical of drug laws (I think -- been years since I checked the record).
