What does ' I do enjoy the regular cocaine mean'?

I have been flirting with one of my guy friends pretty much all day today. It all started last night when we both attended the same party and he was there as a dancer. His group had a show. Later that same night we met down town and we were walking around town wrapping our arms around each other. Our plan was to get into a club but it never happened so we separated ways and went home. Then today we’ve texting each other pretty much all day. It was a pretty intense flirt. Then somewhat through the conversation he said to me “I do enjoy the regular cocaine” what does it mean?
