Jennifer Lawrence has shared her experiences of accidentally taking the wrong medication on film sets, leading to hallucinations and on-set annoyance. During a conversation with Leonardo DiCaprio, she revealed that she once took an Adderall instead of a sleeping pill while filming 'Red Sparrow,' which caused her to stay awake all night and panic. Additionally, she recounted taking an Ambien in the morning, mistakenly thinking it was another drug, during the filming of 'Catching Fire,' which resulted in hallucinations. She noted that her co-star Elizabeth Banks was annoyed with her during that incident. Lawrence also discussed her obsessive need for sleep and her struggles with medication, highlighting the importance of proper medication management on set.
