Former Smashing Pumpkins drummer Jimmy Chamberlin has spoken out about his decision to quit the group last week, revealing he could no longer be a part of something he wasn't "into".

The drummer has opened up about his choice to opt out of upcoming recording and touring commitments with frontman Billy Corgan in a blog post to fans.

He writes, "I can no longer commit all of my energy into something that I don't fully possess. I won't pretend I'm into something I'm not. I won't do it to myself, you the fan, or my former partner. I can't just, 'Cash the check' so to speak."

But he insists he and Corgan have not fallen out over his departure: "My best goes out to Billy and I'm glad he has chosen to continue under the name. It is his right... There is no drama, bad blood."

Corgan and Chamberlin regrouped as Smashing Pumpkins in 2004 after the band split in 2000. The drummer joined the group Corgan founded in 1988 and played on all their albums, except 1998's Adore. He also joined Corgan in spin-off group Zwan.
