The drummer admits the mid-1980s was a ''bad'' time for the 'All Bad Things Must End' hitmakers - which includes Vince Neil, Nikki Sixx and Mick Mars - because they were all ''not waking up'', ''overdosing'' and ''like a bomb ready to go off''.
The 52-year-old rocker is amazed the band - who are in their 34th year together - are living to tell the tale and survived, because he was sure ''someone was going to die''.
He told BANG Showbiz: ''People were not waking up, people were overdosing and people were f***king. Like a bomb ready to go off, like someone was going to die. The fact we made it through that is really amazing because we had all of the ingredients for bad and for something to go extremely f***ing bad.''
The notoriously outrageous rock outfit reached their limits living in Los Angeles, surrounded by ''drug dealers'' and ''distracting'' girlfriends, so moved to Vancouver, Canada, to focus on their music and Tommy thinks it was a good decision.
He added: ''Somehow in 1989 we decided alright we've got to stop and we all decided to get sober and move the f***k away from Los Angeles, move away from the dealers and the girlfriends and the distractions and the bulls*it and we went to Vancouver and made the best record of our lives. That time was probably the baddest.''
