Cover art for Rock On lyrics by 311

My interpretation was that this song is about a drug dealer who has started using his own drugs. (Mainly because of the lines "When you are dealing Back spinning wheels And doing that grind All of the time", which I interpreted as dealing)

And the suggestion that he has started using his own stash:- ("Shot by your own device You pay the price")

I'm not sure what is meant by "The burning of your flesh hits your nose, Now you're bumping"; I know 'bumping' is a slang term for snorting drugs through your nose, but I'm not sure what is causing flesh to burn (Maybe I'm trying to interpret this too literally?)

The multiple references to a "Gun" I'm still wondering about. Is the gun a literal gun (i.e. a handgun/weapon), or a reference to a syringe for injection of drugs?

The song title "Rock On" may refer to "rock" (i.e. Methamphetamine), or it may be a coincidence.
