Comedienne Tina Fey is convinced a "lack of curiosity" has kept her away from drugs - insisting she's never been tempted to experiment.
The 30 Rock creator admits she can understand why so many actors dabble with illegal substances, because life on set can be so "boring".
But Fey is adamant she'll never fall victim herself, because she's just not interested in taking drugs.
She tells Britain's Elle magazine, "(I've never tried drugs) not even a puff. I lack a certain amount of curiosity. I get the idea of not wanting to be where you are, especially on a movie set. It's so boring between set-ups. I do sometimes think, 'No wonder people go to their trailers and take drugs - there's so much downtime.'"
