I doubt it. Those states who have reduced penalties and/or legalized certain drugs are regretting having done so, especially California. Addiction, homelessness and theft crimes are off the charts here, and it all started when voters decided to make all personal drug possession misdemeanors and raised the misdemeanor/felony dollar limit for theft crimes from $400 to $950. There are efforts in the works to repeal these misguided measures.
That having been said.....the justice system is now so overwhelmed and police so understaffed that changing things back won't improve things too much. I could go on and on with specific examples from both my policing career and as a landlord/property owner.
At this point there is so much meth/fentanyl/choose your psychoactive substance around that non-psychoactive drugs like juice are likely not to be prosecuted. You might be arrested and booked, but you're not going to serve a day in jail, pay much of a fine or do community service, or even have to go to court because they will just have you "spit and acquit" (give a DNA sample). In the unlikely event they filed your case, you'd probably get informal probation only (that means you don't check-in, get drug tested or get home visits) and you'd only get in some minor trouble if you broke the law again while on probation.
I guess the bottom line is that it all depends on what state you are in. I just don't see the "let's legalize things" movement spreading when people can point to California and Oregon as perfect examples of why you should not legalize certain psychoactive drugs. California increasingly sucks, but if you get caught with juice, nothing is going to happen.
