"The whole being in limbo thing, I'm over it," Gordon said to ESPN.com's Elizabeth Merrill on Friday. "I'm not waiting on the edge of my seat anymore."
The NFL's leading receiver last season, who was suspended one year after a failed drug test, said he voluntarily checked himself into a rehab clinic in Malibu, Calif., in July, but he does not consider himself a drug addict.
Gordon left the clinic before the 30-day program was complete in order to get to training camp and prepare for his appeal, Merrill reported.
"I think it was before I got into the league," Gordon said when asked about the last time he smoked marijuana. "I don't know."
An arbitrator upheld Gordon's suspension last week.
Gordon said his positive test was the result of secondhand smoke. The failed test was one nanogram per milliliter above the 15-nanogram threshold, Merrill reports.
