"They know she woulda ATE," Drake captioned a photo of the star athlete on his Instagram Story.
Lipa also expressed her displeasure with the U.S. Anti-Doping Agency's (USADA) decision to suspend Richardson after the failed drug test.
"Let her run!! This is stupid," the "Levitating" singer wrote on her Instagram Story.
Union shared a similar sentiment, tweeting, "Weed is great for many a thing but running faster isn't one of them. LET HER RUN!!!"
Richardson's suspension will prevent her from competing in the 100-meter race at the Tokyo Olympics later this month.
As rumors swirled about her suspension on Thursday, the sprinter put out a tweet, simply stating, "I am human." The following morning, she appeared on NBC's Today to issue an apology and offer an explanation for her marijuana use.
"I know what I did. I know what I'm supposed to do. I know what I'm allowed not to do, and I still made that decision," Richardson said, adding that she used marijuana to help cope with her mother's death.
