Researchers say kids whose parents allow them to watch R-rated movies - films for which children under 17 years of age must be accompanied by a parent or guardian - are up to three times more likely to start smoking than those whose parents are more restrictive. They believe this sort of leniency (寛大さ、慈悲)
could trigger smoking by exposing youngsters to depictions (描写、叙述)
of smoking as well as by opening the door to more thrill-seeking, risky behaviors.
