Drugs.

This song is about doing drugs.

Yes you're right, but, more specifically, it's about how she felt peer-pressured into doing drugs. She didn't like it (breathed so deep I thought I'd drown), but she didn't want to seem like a wimp in front of her friends so she just pretended to hit the blunt by biting down on it (it feels better biting down).
