As of 2021, the status of federal legalization in the United States remains a complex and evolving topic. While some states have legalized marijuana for medical or recreational use, it is still considered a Schedule I drug at the federal level. This means that according to federal law, marijuana is illegal and classified as having a high potential for abuse and no accepted medical use.

Despite this classification, there have been some efforts at the federal level to decriminalize or legalize marijuana. In recent years, bills such as the MORE Act and the STATES Act have been introduced in Congress with the goal of removing marijuana from the list of controlled substances or allowing states to set their own policies without federal interference.

Additionally, President Joe Biden has expressed support for decriminalizing marijuana and expunging prior cannabis convictions. However, he has stopped short of endorsing full legalization at the federal level.

The current status of federal legalization in the United States is therefore one of uncertainty and ongoing debate. While public opinion on marijuana has shifted in favor of legalization in recent years, there are still significant legal and political hurdles to overcome before it becomes a reality at the national level.

In conclusion, while progress has been made towards federal legalization of marijuana in the United States, it remains a contentious issue with no clear resolution in sight. It will likely continue to be a topic of debate and discussion for years to come as lawmakers grapple with balancing state rights with federal regulations.
