After 8 years, ‘Weeds’ will go up in smoke

“Weeds,” starring Mary-Louise Parker as a suburban widow who sells marijuana to support her family, ends its eight-season run tonight.

LOS ANGELES — Even after eight years of “Weeds,” the marijuana jokes keep on coming.

Fake joints were handed out at a news conference promoting the series, which concludes the adventures of a drug-dealing suburban widow with tonight’s 10 o’clock hourlong finale.

“I used to say that pot took away from my rent, and now it pays it,” wisecracked cast member Justin Kirk.

For Jenji Kohan, creator and executive producer, the legacy of the show starring Mary-Louise Parker is far more substantive than one-liners.

“We had an extraordinary opportunity to do a half-hour where you didn’t have to have a joke a page. ... We got to do drama slammed right up against comedy, at will,” Kohan said.

“We sort of piloted a new half-hour form, and that was a lovely thing to be able to do.”

“Weeds” certainly was a champion groundbreaker for Showtime, which became home to other series with a similarly dark bent.

It was “the show that set the tone for the current slate of original programming on Showtime,” said David Nevins, the channel’s entertainment president. “It redefined the network and paved the way for a new generation of antiheroes” on “Nurse Jackie,” “Dexter,” “Californication” and more.

It’s also among a rare group of cable TV shows that reached 100 episodes, Nevins said at a celebration of the milestone taping.

How will viewers react to the “Weeds” finale?

“I hope they’ll feel a sense of satisfaction. I hope they’ll appreciate where everyone ended,” Kohan said.
