It would therefore stand to reason that Khloe would be worried about the drugs still being in her house if, in fact, Lamar was using at home.
A new report by RadarOnline says that Khloe was concerned about that and actually hired someone to come check everything out.
"Khloe hired a professional to do a sweep of the palatial estate after booting Lamar from the premises," a source told the site.
"She did this because Khloe didn't want cops to show up with a search warrant and find drugs in the house, because she could be arrested as an accessory, et cetera," they continued.
They also said that in the event that Lamar moves back in the house, she didn't want him to find anything that he had stashed and start using again.
It sounds like Khloe really just wants the best for Lamar, whether that means them staying together or not.
