The cocaine allegation is the latest chapter in a he said, she said scandal that erupted Friday and heated up Sunday with both Ford and Thomson traded barbs in public statements.
Asked by the hosts if she thought Ford was on cocaine, Thomson was blunt.
"I thought he was, yes, but I don't know," she said. "I looked up, I went back and looked up, you know, what are the signs of cocaine use. I looked it up and, you know, sweaty, talking quickly, out of it, arrogant - all these things were on there.
"What I read on Google, I would think he's either on that or some other substance … he was definitely out of it."
Ford's office had yet to respond to a media request Monday about Thomson's cocaine speculation.
Reached by phone Monday, Thomson stopped short of saying Ford was on cocaine.
"I have no idea what he was on," Thomson told the Sun. "I know he was intoxicated. I went home and looked up a bunch of things over the weekend. I looked up what could it have been trying to understand why he would treat me that way."
"I don't know what it was, I was looking at the way he was treating me and I looked up what the effects of cocaine," she added.
