In a conference call with reporters, Mayock added that habitual use of any drug remains a worry among teams executives.
"If it was a one-time thing and not that big a deal, then it's not like you're beating women or you're a convicted felon or murdering people," Mayock said, according to the Detroit Free Press. "There's hot-button issues now, but I don't think one time with pot is a hot-button issue. (If) it's more habitual, then it's more what are we going to have to deal with if this guy really likes pot, and he gets banged a couple times? We're going to lose him off the field."
The Lions have the 23rd pick in next week's NFL draft, and must evaluate players with marijuana incidents in their background -- especially at cornerback, where they need help the most.
The Lions brought both Kirkpatrick and Adams in for pre-draft visits, and Kirkpatrick told the Free Press on Wednesday that his arrest hasn't been a big deal.
"They know I was just in a bad place at the wrong time," he said "... The charges have been dropped, so ain't nobody stressing about it."
