So, 2022 is actually after 2020, when

Nobody should be in jail for smoking marijuana," Biden told voters at a Tuesday house party in Nashua, New Hampshire.

Asked by CNN if the former vice president supports legalizing marijuana, Andrew Bates, a Biden campaign spokesman, said Biden believes the drug should be decriminalized

I'd encourage you to read more than a soundbite especially if you're looking for specifics. Here's an actual interview transcript with Biden from May 2020, interviewed by Charlamagne tha God no less, where he asks the specific question of Biden and receives the specific answer:

Charlamagne tha God: (15:42) Vice President Biden, I've read some of your black agenda and you say that you would decriminalize marijuana. What's the difference between legalizing it and decriminalizing?

Joe Biden: (15:51) Because they're trying to find out whether or not there is any impact on the use of marijuana, not in leading you to other drugs, but what it affects. Does it affect long term development of the brain and we should wait until the studies are done. I think science matters.

Biden does make the distinction that he's not going for full legalization, and further, that he's going to defer to science instead of making the call himself.

Biden lowered marijuana from a Schedule I to a Schedule III drug.

Which isn’t what he promised to do while campaigning, and the difference between descheduling and rescheduling enabled this arrest and prosecution, which is exactly how Biden wanted it because he is and always has been racist fucking scum who has fought to preserve law enforcement’s ability to harass black people

He didn't promise it deschedule it.

he did a mass federal pardon for past federal

Uh huh

As far as bold acts of mass clemency go, it won’t lead to many people getting out of prison. In fact, it will lead to none. According to the White House and a report this week from the U.S. Sentencing Commission (USSC) there is no one currently in federal custody for simple possession of marijuana.

Weasel words in your sentence. "In fact, it will lead to none." A pardon is far more than letting someone out of jail. Its removing the stain of the conviction from a persons record enabling them to seek employment without having to report it, pass background checks for jobs that require it, and makes you eligible for subsidized housing with that conviction removed.

"In addition to individual pardons, Biden granted clemency to 6,500 individuals convicted of simple marijuana possession under federal law, part of his broader initiative to address racial and systemic inequities in drug enforcement"

6500 people received the benefit of that pardon because the pardon went back all the way to 1992 convictions. Your own linked-through source says the number of pardoned people is 6577 Why didn't you mention that and instead just quote your "no one" sentence?

Are you going to counter that 6577 people is almost no one? I don't necessarily disagree, but that's because most simple possession charges are state or local offenses where the President of the United States has no pardon power. Again, your own source says this. If that's your beef, take it up with states and cities.

Joe Biden is and always was a fucking asshole

All politicians are assholes, but Biden's actions helping Americans' interactions with marijuana in the legal system are more progressive and a larger improvement in our society than any other President in over 60 years. You can complain that he didn't do enough, but I think its disingenuous for you to portray the positive actions forward and nothing.
