The 38-year-old-singer said that despite being around people who use such substances regularly, he is never fascinated towards it, reported Contactmusic.
"I was never tempted by drugs. The amount of times I've been asked, 'You don't do coke? But you're in music," he said.
Iglesias says he knows the skill to control himself after consuming alcohol.
"I don't like sticking stuff up my nose. Get me a drink, get me a rum. I drink, I'm a social drinker but I feel like I can control it. There are friends of mine who go out at the weekend and do a lot of cocaine and do any drug and be perfectly fine throughout the week," he added.
