High School Musical: The Musical: The Series alum Joshua Bassett is detailing his dependency to ketamine after his near-fatal cardiac episode in 2021. "My reckless addictions rapidly spiraled, relentlessly growing worse and worse and worse," Bassett, 25, wrote in a poem titled "Jesus open his eyes" in his new book Rookie: My Public, Private, and Secret Life. "The high highs and oh-so-low lows eventually caught up to me in New York." Bassett was hospitalized for heart failure and septic shock in January 2021 weeks after his 20th birthday.
