Sorry to burst your bubble here, but the house did not pass a law. They passed a BILL. That does not make it a law.
And you can believe what you want of all the fairy tale promises and political BS out there, or you can listen to what Biden himself said. As in recent quotes like this:
“The truth of the matter is, there’s not nearly been enough evidence that has been acquired as to whether or not it is a gateway drug,” Biden said,
(Joe Biden Claims Marijuana Might Be Gateway Drug, Despite Research - Business Insider).
And Biden has made a career out of having a hard line on drugs. Perhaps you missed that in the 20th century? In 1989, senator Biden went on national television criticizing a plan from President Bush I to escalate the war on drugs. According to Biden, the plan didn’t go far enough. Quote: “Quite frankly, the president’s plan is not tough enough, bold enough, or imaginative enough to meet the crisis at hand.” He called not just for harsher punishments for drug dealers but to “hold every drug user accountable.” As the head of the Senate Judiciary Committee in the late 1980s and early ’90s, Biden did not just support the war on drugs and mass incarceration; he wrote many of the laws that helped build a punitive criminal justice system. That included measures that enacted more incarceration, more prisons, and tougher prison sentences for drug offenses.
Those are Biden facts… not promises or wishful thinking position statements.
