Quinn's first year in the industry took place prior to her 18th birthday. Eighteen is the legal minimum in which United States citizens may appear in pornography. Like the case of Traci Lords that came several years earlier, it was discovered in the early-1990s that Quinn's earlier films were made before she was 18. According to a 2000 interview with Quinn, the discovery occurred when she forgot to bring her fake ID to a session and used her real ID, thinking they would not notice the difference.
Videos featuring the underage Quinn were removed from the market. Many were edited to remove all footage of Quinn and re-released (examples include the John Stagliano-directed Buttman's Ultimate Workout and John Leslie's Curse of the Catwoman). Amid the controversy, Quinn left the porn business for a time. She resumed her pornographic career in the mid-1990s. She was still an active pornographic actress as of 2006, usually playing the role of "the older woman."
Reportedly, Quinn at one point was hired to reshoot some of her pre-18 scenes in order to keep her films in circulation.
