Glennon alleged in the documents that Portwood “went to her drawer and took a handful of Klonopin and tossed it back like it was nothing,” during the dispute.

After he told her that he “was going to call for help,” Glennon said Portwood “regurgitated the pills.”

Then, Portwood “picked up a machete towards him and [James],” the documents read.

A source previously told PEOPLE thatdrugs were not a factorin thealleged violent dispute.

“The situation is a little more complicated than what’s been reported. There was an argument that escalated and now they aren’t allowed to communicate,” the source says. “There were no drugs involved.”

“This is a very challenging time for Amber, who loves her son more than anything,” the source added. “Now she will need to determine next steps following what just occurred, but she has a great lawyer.”
