The cover of the album One-X includes a quote by Adam that states: I'm on the edge and falling off/and I'm sick of feeling numb/Help me believe it's not the real me/Maybe we can turn it around/Cause it's not too late/I'm standing here alone/feeling so stepped on/It wont be long until I'm burning on the inside/I just don't care anymore/That it drags me down/Things are clear/I will not die/We are one. The quote contains lyrics from songs off the band's second album, One-X. In 2005, Adam went into rehabilitation for an addiction to OxyContin at the Toronto rehab center CAMH (Centre for Addiction and Mental Health), which is where many of the songs for One-X were written, including "Pain", "Animal I Have Become", "Over and Over" and "Gone Forever".

In early 2009, Gontier was said to have co-written a song with Chris Daughtry that would appear on Daughtry's new album Leave This Town. When the album was completed, it was revealed that Adam's song wouldn't be in it. Instead, it was released as a b-side of Daughtry's new single, "No Surprise", and in United Kingdom iTunes Stores. The song is called "Back Again". Three Days Grace released their 3rd album entitled Life Starts Now on September 22, 2009.
