Gordon, 23, served a 10-game suspension after testing positive for marijuana use during the offseason. He was previously suspended two games last season for violating the league's substance abuse policy.
In an interview with the NFL Network that will air Saturday morning, Gordon said he has noticed a difference in how some people interact with him.
"The lowest point of all this I think was the disassociation from a lot of friends you thought were close or you thought you were kind of cool with really not checking on you anymore, [not] hitting you up anymore, [not] wanting to hang out,'' Gordon says. "As far as even people in here [with the Browns], I don't want to throw names around, but I can see it.
Gordon made his season debut last week against the Atlanta Falcons and caught eight passes for 120 yards. He led the NFL with 1,646 receiving yards last season and also had nine touchdowns en route to being selected a First-Team All-Pro.
In Gordon's absence, Andrew Hawkins became the team's leading receiver with 694 yards and two touchdowns, while Taylor Gabriel added 527 yards and a touchdown.
Cleveland plays at Buffalo on Sunday.
