Everything But

Someone who does a lot of every kind of drug but refrains from taking the infamously addictive and destructive drug, Heroin.
Someone who's does "Everything But" is usually proud or happy of the fact that they avoid Heroin; yet are clueless to how damaged they are from all of the other drugs they take. They live in blissful ignorance.

"Yo, you hear that Katie OD'd on H last week?"

"Oh damn dude, I thought she did Everything But"
