STEVE INSKEEP, HOST:
We have news of an unintended effect of sin taxes - you know, taxes on alcohol or cigarettes. Lawmakers reluctant to raise any other taxes do raise those, which seems so worthy - discouraging bad habits or doing something else. NPR social science correspondent Shankar Vedantam is here. Hi, Shankar.
SHANKAR VEDANTAM, BYLINE: Hi, Steve.
INSKEEP: What happens instead in some cases?
VEDANTAM: Well, in some cases, people do quit or smoke less or cross state lines to buy cheaper cigarettes across other jurisdictions.
