Panic! At The Disco drummer Spencer Smith has pulled out of the rockers' current U.S. tour to allow himself extra time to deal with his drug and alcohol addiction.

The percussionist went public with his substance abuse struggles in July (13) in an open letter to fans, revealing he began popping pills and drinking heavily to combat feelings of anxiety and depression.

He checked himself into a rehabilitation programme last year (12) in a bid to address his problems, and a newly-sober Smith recently rejoined his bandmates on the road for their summer (13) trek with Fall Out Boy.

However, after performing a handful of shows with Panic! at the Disco, Smith has chosen to sit out the rest of the group's live dates to continue his recovery away from the pressures of the spotlight.

Frontman Brendan Urie broke the news to fans in a post on the group's official website late on Wednesday (08Aug13), writing, "Spencer and I have been through a lot of hurdles together, but witnessing one of my closest friends immersed in such a battle has been the most difficult...

"It's become evident Spencer still needs more time to take care of himself. I can't expect him to be fighting addiction one minute and be fully immersed in a national tour the next. With all that said, the tour will continue without Spencer while he is away getting the help he needs. Thank you all for your support and kind words."

It is not yet clear who will replace Smith on drums for the band's next show in Jacksonville, Florida on Friday (09Aug13).
