The 1984 Pepsi commercial itself did not directly cause Michael Jackson's downfall or death, but it was a significant event that had lasting consequences on his health and career. During the filming of the commercial, a pyrotechnics accident caused severe burns to Jackson's scalp. This injury led to a lifelong struggle with pain and the use of painkillers and other medications. Some reports suggest that the trauma from the accident contributed to his later dependence on prescription drugs. While the commercial boosted his popularity and was a major endorsement deal, the physical and psychological impact of the accident played a role in the challenges he faced in subsequent years. However, Jackson's downfall and death were the result of multiple complex factors including personal, medical, and professional issues, not solely the Pepsi incident.
