Metalheads Just a question I need answered?

Ok, fellow Metalheads, I usually listen to Death and Thrash Metal. I usually hang out with Scandinavian(mostly norwegian) and they pretty much do these hard liquors like Vodka and smoke a lot of weed. I'm clean,but this is where my question comes in. Since I'm a Metalhead and all, do I have to do drugs to be a 'Metalhead'?
