I didn't think you could get cough syrup with codeine in it in any state over the counter. I am probably mistaken but every time I've gotten stuff with codeine in it it's been prescription. And I've gotten it in probably 7 or 8 states. But I guess the states I got it in are the states that you would think might be on the stricter side.
On another note, despite supplying you with this info (or lack there of), you are an idiot for asking. Go smoke a joint. It can't kill you. Over the counter and prescription drugs can.
