The evidence in words
Safety profile
Highly addictive; raises heart rate and blood pressure; toxic in overdose (especially liquids around children). Not for anyone nicotine-naïve, pregnant, or with cardiovascular disease.
Interactions to respect
No major interactions are on record for Nicotine at typical doses, but tell your clinician about everything you take.
What Nicotine is
Nicotine is the addictive alkaloid in tobacco, also delivered via gum, patches, lozenges and pouches.
The honest bottom line
A real attention enhancer with an unusually bad addiction and cardiovascular profile. If you don't already use nicotine, the cognitive benefit is not worth the dependence risk.
