President Trump has signed an executive order that could reclassify marijuana as a less dangerous drug. This move could ease regulations and expand medical research by shifting marijuana from a Schedule I drug, like heroin, to a Schedule III substance, similar to ketamine. This change won't legalize recreational use nationwide but may alter regulation and taxation. President Joe Biden's Justice Department had also proposed reclassifying marijuana, but Trump’s order on Thursday could speed up the process,. Some Republicans oppose the change, arguing marijuana remains dangerous. Trump has focused on combating other drugs, like fentanyl, during his second term.
