Actually, in regards to Anark's post about junkies 'keeping up with the Jonses', it's actually the other way around. They'd be 'keeping away from the Joneses', 'keeping ahead of the Joneses or 'keeping the Joneses at bay'...

The Joneses is a slang title given to The Sick, The Ill, aka withdrawl. As in 'I've got these Joneses killing my boneses', a term used by addicts when they're hurting for a fix. Instead of considering the Joneses to be an ideal life type or style, junkies consider it the enemy.The perfect drug would be one that didn't induce withdrawl effects.
