A 90-year-old man smoking pot on Mount Tamalpais this past July 3 sparked a blaze that set his clothes and the hillside around him on fire, according to the August edition of Tamalpais Guardian published by the Tamalpais Conservation Club.

Were it not for a north wind that blew it toward the shore of Lake Bon Tempe, the two-acre fire could easily have spread through the watershed and the Cascade Canyon area of Fairfax, The Marin Independent Journal reported at the time.

 Of the various criticisms aimed at pot, its potential to start wildfires is not usually among them. But not all dangers are obvious. I just read about the danger of eating too much melon. Pope Paul II in 1471 died in the Vatican from a fit of apolexy after indulging his appetite for melons, writes historian Ross King in The Bookseller of Florence.

On the other hand, “some — mainly the pontiff’s critics — said that he had died [of a stroke] whilst being sodomized by a page boy,” according to Wikipedia. Another unrecognized danger, I suppose.
