According the the Centers for Disease Control and Prevention (CDC), characters in Hollywood movies — whether they are in G-rated movies or R-rated flicks — are far less likely to smoke than in years past.

According to the CDC, smoking in movies rated G, PG and PG-13 fell 71.6 percent between 2005 and 2010, from 2,093 incidents in 2005 to 595 in 2010. In films rated G or PG, incidents of tobacco use declined 93.6 percent, from 472 to 30. The biggest gains were from three studios in particular who developed policies on the use of smoking in films. 

Time Warner, Universal and Disney each have policies on smoking in films. Among these movie studios, the use of tobacco in youth-related films declined 95.8 percent between 2005 and 2010. The three remaining studios who do not have policies on smoking — Viacom, News Corp. and Sony Pictures — saw a decline of 41.7 percent.

Like it or not, kids and teens are influenced by the movies they see, and that influence extends to early decisions about whether to start smoking. "The more you see, the more likely you are to be open to smoking and start smoking," explained one of the study's authors, Ursula Bauer of the CDC.

Fewer smoking scenes in Hollywood movies means kids and teens will have one less reason to start smoking. Sounds like a blockbuster hit to me!
