>One can really just eat cigarettes to die?
Yes.
Although you'd probably need to take a strong anti-emetic beforehand. One of the major symptoms of nicotine poisoning is heavy nausea, so there's a good chance you'd vomit before your body has fully absorbed all the nicotine.
As for how many you'd need to eat? The lethal dose of nicotine ranges from about 500 to 1000mg and an average cigarette contains 20mg, so you'd need to eat anywhere from 25 to 50.

It's not a fun method. Only go for it if you're absolutely desperate and the only other choices available to you are even worse than death by nicotine.
