R+B singer Amerie avoids drug-fuelled parties because she fears impure environments will damage her voice.

The 1 THING beauty ensure she steers clear of scenes of excessive decadence as such behaviour runs contrary to her religious beliefs.

And Amerie even believes drug takers should be punished in a biblical fashion.

She says, "Sometimes I'll walk into a party or a club and I'll just say SODOM AND GOMORRAH to my friends.

"That happens when you go to recording studios, but I move away. I can't have anyone smoke near me because it affects my voice, so it just isn't anything that would tempt me."
