The 63-year-old said that he felt he'd lost part of his brain when he smoked marijuana first, reported Femalefirst online.
"I'm not better than the next person. But I've never had a desire to do drugs. When I was 21, I smoked marijuana and I didn't like the way it made me feel. When I woke up the next morning I felt like I'd lost part of my brain," he said.
Wonder also said that he has never had any interest in taking drugs as the one time he dabbled with illegal substances, made him hate the effects.
