Is nicotine considered an intoxicant?

There's two questions about haram nature of smoking cigarettes https://islam.stackexchange.com/q/918/17163 and https://islam.stackexchange.com/q/16815/17163 . However, none of the answers address whether or not nicotine is considered an intoxicant. Wikipedia writes: > Nicotine's mood-altering effects are different by report: in particular it is both a stimulant and a relaxant. First causing a release of glucose from the liver and epinephrine (adrenaline) from the adrenal medulla, it causes stimulation. **Users report feelings of relaxation, sharpness, calmness, and alertness.** It's not clear from this whether or not nicotine is an intoxicant. A relevant hadith is *The Prophet [SAW] forbade a small amount of whatever intoxicates in large amounts.* Sunan an-Nasa'i 5609 (grade: hasan). And certainly, a "large" amount of nicotine causes nicotine poisoning (actually it's quite small: "0.5-1.0 mg/kg can be a lethal dosage for adult humans"). But I'm not sure if "poisoning" would be considered "intoxication". **Question**: Is nicotine considered an intoxicant?
