Has no one really died from using marijuana? Here's a sad story from the San Jose Mercury News:

"SANTA ROSA, Calif.—The man who piloted a small plane that crashed near Fresno last year, killing himself and two others, had a significant amount of marijuana in his system at the time, according to a coroner's report.

Karl Esposti, 50, of Windsor, was flying his Cessna T-210L Centurion above the farming town of Tranquillity on April 7 when the plane encountered bad weather and crashed in a wheat field, authorities said."
