Whitney Houston is among the most popular artists of all time, but still died of a drug overdose. Houston was found alone in her bathtub in February of 2012. After a brief police investigation, the toxicology report showed her cause of death was drowning after loss of consciousness relating to cocaine interacting with her heart condition (atherosclerotic heart disease).
Houston’s behavior had been called into question for several days previous to her death, with onlookers describing her as “erratic” and “disheveled”. The toxicology report also showed evidence of longer-term drug use, including Benadryl, Xanax, Flexeril, and cannabis.
