I suspected but could not find them.  The reason I suspected is I found matches etc.   What I did find was a lot of liquor bottles and portable breathalyzer.
  Stuff you would find from a 16 year old rebellious teenager...except she was a middle aged mother.   Eventually she learned to store stuff at a friends or the girlfriends place.  
 

I think it's common with anyone who wants to escape their own reality.
