Josh Hamilton says that doctors have told him his allergy issues haven't been caused by past drug use, according to the Los Angeles Times.
Hamilton has been sick with sinus congestion that makes him prone to dizziness and sensitive to the lights at major league stadiums.
"You have a hallway up the middle of your nose and sinus cavities on each side," Hamilton said. "When you breathe air, it goes up and down the hallway.
"Same thing when you do drugs, it goes up the hallway, not into the sinus cavities. I told the doctor I had never had allergies before I started doing any of that stuff, but he said [drug use] has nothing to do with it."
