Why are there so many songs titles where the word "love" can easily be replaced by the word "drugs?"?

Im crying because i cant stop laughing! Hahahaha. I was just listening to My love - Justin Timberlake, Haha. "alll i want you to do is be my drugs,(so dont give away) my drugs,(so dont give away) my drugs,(so dont give away) My druuuuugs, my druuuugs, my druuuugs...." Then Love bomb - N.E.R.D, "dont need another drug song, we need a drug bomb. To just blow us away, to f*ckin blow the lights out..."
