As of now, the latest cannabis legalization update in the United States is that more and more states are moving towards legalizing recreational marijuana. Currently, there are 18 states along with Washington D.C. that have passed laws allowing for the adult use of cannabis. This number is expected to grow even further as public opinion continues to shift in favor of legalization.

One of the most recent developments in cannabis legalization is New York becoming the 15th state to legalize recreational marijuana. Governor Andrew Cuomo signed a bill into law that allows for adults over the age of 21 to possess up to three ounces of cannabis for personal use and allows for sales at licensed dispensaries. This move is seen as a significant step forward in ending the criminalization of marijuana and creating a regulated market for its sale.

In addition to New York, other states such as Virginia, New Mexico, and Connecticut have also recently passed laws legalizing recreational marijuana. These states join others like Colorado, California, and Oregon who have already established successful legal cannabis markets.

The momentum towards cannabis legalization in the United States shows no signs of slowing down. Polls consistently show that a majority of Americans support legalizing marijuana, and lawmakers are taking notice. With more states moving towards legalization, it is likely that we will continue to see changes in federal policy regarding cannabis in the coming years.

Overall, the latest update on cannabis legalization in the United States is one of progress and momentum. As more states choose to legalize recreational marijuana, it becomes increasingly clear that attitudes towards cannabis are evolving and that prohibition may soon be a thing of the past.
