On November 5, 2007, it was confirmed that Showtime would air a fourth season of Weeds, to contain at least 13 episodes.[10] The fourth season started airing on Monday, June 16, 2008 with the final episode airing on Monday, September 15, 2008.[11] The first episode of this season, entitled "Mother Thinks the Birds are After Her,"[12] was the last time "Little Boxes" was used during the opening credits. Thereafter, each episode began with an animated title card in a scenario relating to the episode. Major changes to the cast were made, owing largely to the family's move. Mary-Kate Olsen and Matthew Modine no longer appeared in the show, and Romany Malco and Tonye Patano, who had key roles in the first three seasons, were no longer part of the main cast, and remain unseen. Albert Brooks was added as Andy's father, Lenny Botwin, who was seen in the first four episodes of the season. Guillermo Diaz and Jack Stehlin, who played minor recurring roles previously, play larger roles.

Nancy relocates her family to the fictional town of Ren Mar, located on the San Diego/Tijuana border,[13] after having set fire to her house and burning it down. She begins drug trafficking across the border for Guillermo, and must deal with Celia, who has been sent to spy on her in hopes of getting herself out of jail after Celia takes the fall for Nancy and Conrad's grow house. Andy begins a coyote business with Doug, who has moved to town to evade questions about Agrestic's finances. Silas sets up his own weed business and begins dating a local gourmet cheese shop owner, who is almost old enough to be his mother. Isabelle moves in with Celia because they will live near the beach. Shane has difficulty adjusting to the new location and pushes away Isabelle and Nancy, making friends with two more "dangerous" girls at school.

As the season progresses, Nancy's role changes as Guillermo's boss sets her up as a money-laundering front in a maternity store and Celia works there as a cashier. Guillermo's men catch Celia spying on them and Nancy convinces them to spare Celia's life. The maternity store is the endpoint for a drug trafficking tunnel to Tijuana, Mexico. When Nancy realizes that the tunnel is also being used to smuggle guns and young girls for prostitution, she decides to inform DEA Captain Roy Till, despite having a sexual relationship with the corrupt Mayor of Tijuana, Guillermo's boss Esteban Reyes. The DEA raids the maternity shop and a bloody shootout leaves most - but not all - of the Mexican drug runners dead.

During this time, Doug and Andy's coyote business becomes very successful. Andy is worshiped by the immigrants they smuggle while Doug even manages to fall in love with one of the immigrants he named "Mermex". To his chagrin, the illegal immigrant falls for Andy instead of Doug, as Doug's personality, genital warts and unapologetic nature turn her away.

Meanwhile, Celia begins to develop a drug addiction and it becomes bad enough to prompt Isabelle and Dean to stage an intervention. After some initial reluctance, Celia starts to attend rehab and apologizes to Isabelle and Dean. However, Dean rejects her apology and instead suggests she say she is sorry to Quinn, who is still in Mexico after Celia sent her to boarding school at the end of the pilot episode. Celia decides to do so in the season finale but upon her arrival she is drugged and kidnapped by Quinn for revenge.

In the season finale, Nancy is called into the DEA for questioning. Roy Till threatens to kill the person responsible for his partner's death. Esteban, the mayor, discovers Nancy is the person who told the DEA about the drug tunnel. Moments after being confronted, Nancy informs Esteban that she is pregnant with his child, and that she thinks it's a boy. Back at home, Shane steals Silas' weed and started selling it to other kids with the two girls he met. Doug alerts the police to Mermex's illegal immigration after she rejected him and believes that his life has hit rock bottom. Doug realizes that having nothing means the people that are after him will not gain anything from pursuing him, and writes a letter to his separated wife daring her to bring it on. Andy contemplates whether or not he is in love with Nancy and questions his reasons for staying with the family for so long
