Saving money as a reason to quit smoking

Howdy, I’ve always considered myself a frugal person in most aspects of my life. I never eat out, don’t spend money on clothes and prefer lost cost entertainment. I have however kept a nasty habit off smoking that I haven’t been able to kick. I feel like it doesn’t make sense to spend money on this since I’m so frugal and that’s what I tell myself when I try to quit but it hasn’t worked so far (and I’ve been trying for years). Wondering if anyone else has had this experience/maybe has some advice. Seems like I can do anything to save a few bucks and it’s really frustrating
