Did The Washington Post publish an article by Hunter Biden titled "New Studies Show Moderate Crack Cocaine Use Not A Cause For Concern"? No, that's not true: The headline of an article purporting to be on the Washington Post website is fake. A search of the newspaper's website yields "0 results" for the headline. The addition of Hunter Biden as a byline is a sarcastic reference to President Joe Biden's son, who has admitted to drug addiction, including crack cocaine.
The claim appeared in a tweet (archived here) on July 11, 2022. It opens:
Incredible
This is what the post looked like on Twitter at the time of writing:

The post shows a screen grab that appears to be from an undated Washington Post article, which does not exist. Using Google to search the headline plus Washington Post yields no results, as does a search on the Washington Post website.
The caption of the photo "Cisgender African American holding crack - Source: Reuters)" is fake. The real photo is an Associated Press image published in an August 21, 2019, USA Today article with the caption, "A small bag containing crack cocaine. Damian Dovarganes, AP."

The Hunter Biden byline on the article is a satirical reference to President Biden's only living son. Hunter Biden has confessed to his previous extensive crack use in his autobiography as well as multiple interviews.
