Nicotine plays a role in the parasympathetic nervous system, principally through its actions on the autonomic ganglion, which stimulates the parasympathetic nervous system and, as a result, its terminal actions on various organ systems involved in rest and restoration. These effects include the stimulation of the sex organs in the male. Acetylcholine is responsible for arousal and erection via the parasympathetic nervous system, while epinephrine is responsible for orgasm and ejaculation via the sympathetic nervous system, both of which respond to nicotine. Nicotine has long been thought of as an aphrodisiac, and this explains why. The taking of nasal snuff is possibly the most effective nicotine delivery system to the autonomic ganglion, the finely milled tobacco being so readily absorbed by the mucous membranes of the nasal passages. Some male snuff takers have reported becoming aroused, erect, and close to ejaculation, on taking large sniffs of nasal snuff tobacco that contained a high nicotine content.
Can anyone here relate to these findings?
