I knew Andrew well between 2002 and 2007 and I never saw any signs of addiction, but after he died, I read speculation that he might have been using substances.

There’s no definitive evidence that Andrew Breitbart died due to an addiction. Breitbart, a well-known conservative commentator and founder of Breitbart News, passed away on March 1, 2012, at the age of 43. The official cause of death, as determined by the Los Angeles County coroner’s office, was heart failure due to hypertrophic cardiomyopathy—a condition where the heart muscle thickens, making it harder to pump blood. The coroner’s report also noted that he had a small amount of alcohol in his system (a blood alcohol level of 0.04%), but this was not considered a significant factor in his death.
Speculation about addiction has circulated over the years, often fueled by his high-energy persona and some anecdotal accounts from those who knew him. However, no credible evidence—such as toxicology reports pointing to drug overdose or statements from close family—supports the idea that addiction directly caused his death. His wife, Susannah, and others close to him have consistently described his death as a result of natural causes tied to his heart condition, which he may not have known about prior to his collapse.
