Rolling Stone celebrated 4/20 this week by digging into the politics of pot in America, as well as its place in popular culture. We counted down the 15 best stoner songs of all time, discussed "offshore" pot smoking with Bill Maher, gave some serious thought to the issue of marijuana reform in the United States and went over the numbers of pot-related statistics.

Rolling Stone was also at some of the week's hottest concerts, including the Coachella Festival in Indio, California. You can check out all of our coverage of that event – including exclusive interviews and photos – on our Coachella festival blog. We also caught PJ Harvey's show at Terminal 5 in New York City, Paul Simon's set at the Music Box in Los Angeles, Elton John's free concert at the opening of the Tribeca Film Festival in Manhattan and Iggy and the Stooges' tribute to their late bandmate Ron Asheton in Ann Arbor, Michigan.

We also talked to director Michael Rapaport regarding his controversial documentary about A Tribe Called Quest, conversed with Jennifer Lopez about American Idol and her forthcoming album, chatted with Tom Petty about his Sirius FM radio show, caught up with Cameron Crowe on his Pearl Jam Twenty documentary and checked in on Anthrax's progress in making their first record in eight years. Plus, Southern rapper Big K.R.I.T. was named our latest Artist to Watch, we analyzed this week's pop charts, looked back on this week in rock history and, as always, we reviewed all the week's biggest new releases.

On the pop culture front, Peter Travers praised Morgan Spurlock's new documentary, Pom Wonderful Presents: The Greatest Movie Ever Sold, a film about product placement that is very silly and funny but also eye-opening and depressing. Travers also reviewed the glossy but dull Reese Witherspoon vehicle Water for Elephants and the featherweight animated feature Rio. Also, Mallika Rao commented on the contestants' theatrical antics and the dismissal of Stefano Langone on this week's episodes of American Idol and Erica Futterman recapped the latest episode of Glee.
