Have you tried r3vl0n black cherry? Depending on what gloss you use, it can transform from a medium deep red to berry to oxblood. If you blot and add red gloss, it makes the perfect slightly deeper than classic red lip. If you add a pigmented fuschia gloss to it, it turns a beautiful berry that leans raspberry. If you add a dark red to it, you can get a really nice deep 'oxblood'. If you add something orchid like, it brings out the purple. It is a cheap drug store option and I bet with the right layering, you can get it to the exact color of love drug. If you don't want to work for it, Marc Jacobs lip gel in 128 is close, if you want sheer tarte lip surgence in moody (but you can get that color easily with the r3vl0n), and mixing fresh balms in plum and berry would get you there too. As for an exact dupe, I'm afraid I cannot help. I'd look into the new line of bareMinerals lipsticks and the new line of urban decay lipsticks, UD usually does nice berry's and so does bare minerals imo. I had a lipstick from bare minerals that was the exact same shade, but they discontinued the line, but maybe the color passed over to the new line. if you can get into a store, I'd check it out.
Check out Dior Addict Extreme Lipstick in Black Tie, or maybe Sunset Boulevard if BT is too purple (if you can't get a good idea of the color on here, do an image search for a swatch). If that's too intense, maybe Clinique Almost Lipstick in Black Honey? Since it's semi-sheer, you might want to try it out in person to see how it looks on you. Hope that helps ... I haven't seen the nail polish in person, I'm just going from your description & the picture.
