Plot. Days before the trial of accused rapist Luke Ronson (Andrew Howard), the prosecution's primary witness Annette Fox (Alice Barrett) is murdered while shopping with her daughter, Jenna (Hayley McFarland). Detectives Olivia Benson (Mariska Hargitay) and Elliot Stabler (Christopher Meloni) are called in to investigate the correlation between the murder and rape case and assure Jenna they will catch her mother 's killer. Ronson, now a volunteer barber at a homeless shelter run by Sister Peg (Charlayne Woodard), says the sex was consensual. The detectives search his house and find a gun and black hoodie similar to the one Fox's killer wore. However, owning an unloaded gun without a permit is a misdemeanor, not enough to keep Ronson in holding, and the gun does not match the murder weapon. Stabler and Fin Tutuola (Ice-T) follow Luke to the shelter and watch him argue with a man, Eddie Skinner (Michael Raymond-James), who earlier said he saw Luke with a  gun the night of the murder. When Skinner sees the detectives, he tries to run, but they arrest him. Ronson says he hired Skinner to scare Annette, not kill her, but Skinner says he and Ronson never agreed to that. Benson believes Ronson, but with no murder weapon, SVU has no case. ADA Sherri West (Francie Swift) charges Ronson with witness tampering and Skinner with assaulting a police officer. Later, ATF Agent Greer (Pedro Pascal) takes custody of Skinner because he is the key to busting a cigarette smuggling ring. Stabler goes undercover to bust the smuggling ring using Skinner  as bait, but the paranoid smugglers suspect Stabler of being a cop and open fire on him; Skinner escapes during the chaos. The detectives track Skinner to Ronson's apartment, where he holds Ronson at gunpoint demanding money. Stabler convinces Skinner to put the gun down and arrests both men. Skinner admits to killing Annette in exchange for a lesser murder charge, and tells detectives that he got the murder weapon from Greer. Greer is arrested as an accessory to murder and put in holding with Ronson and Skinner. Sister Peg visits the station to drop off a picture of  Jenna and Annette with an address written in Skinner's handwriting. The detectives call Jenna into the squad room so she can see the three men behind bars. She leaves, but surprises everyone by returning with a handgun and firing wildly into the holding cell, killing Ronson and Greer. As Benson pleads with Jenna to put the gun down, Stabler takes cover behind his desk and reaches for his weapon. Jenna fires one shot at them, hitting and killing Sister Peg. Shocked, she stops, but a provoking comment by Skinner infuriates her again. As she aims her gun at him , Stabler shoots her. As she lies on the floor, Jenna says she bought the gun off the street before dying in Stabler's arms. Production.

Baer, who signed a three-year deal with CBS Television Studios in November 2011, was replaced by former "" executive producer-showrunner Warren Leight.

A plan to have Hargitay only appear in 13 episodes of the was discussed but later retracted, as Hargitay then extended her contract through the . Neal Baer told Michael Ausiello about the twelfth season finale, "We go out with a bang. It's my last episode for "SVU" — I'm leaving after 11 years to go to CBS — and it leaves us with a death; it  leaves us with one of our beloved characters doing something that will change the way they see being a cop; and since I'm a [doctor], I get to rag on cigarettes, so that's terrific!" The month before, Ausiello hinted that there would be a fatality on the show. At the start of 2011 when "SVU"'s future was unknown, Baer said of Hargitay and Meloni's status on returning with the show, "They're the longest running drama duo in TV history," Baer continues, "and I think [they'll be around] as long as they can keep playing  new angles within the parameters of the show." And as the credits showed that Baer did not write "Smoked", he commented, "I don't have plans to write some farewell show,” he laughed. "It will just be a really good, twisty, turny and hopefully memorable episode."

Critical response. Lucy Tonic of "Yahoo" said: "'Smoked' ends with chaos in the precinct, resulting from a literal smoking gun, yet it's unfortunate that writers tried to introduce the issue of America's gun problem within the last ten minutes of  the episode.
