Comparison
Modafinil vs Nicotine
Modafinil
A eugeroic — a wakefulness-promoting compound — originally developed for narcolepsy. The most-studied prescription cognitive enhancer outside of ADHD treatment. Produces 12–15 hour windows of sustained alertness without the euphoria, abuse potential, or cardiovascular load of amphetamines. Prescription-only in nearly every jurisdiction.
Nicotine
Naturally occurring alkaloid found in tobacco. Potent cognitive enhancer with mostly favorable acute effects; addiction risk is the main issue.

Bottom line
Modafinil (evidence A, safety 3/5) matches the evidence base of Nicotine (evidence A, safety 2/5). Modafinil has the slightly cleaner safety profile. For users new to either, the higher-evidence option is the safer first try.
Choose Modafinil if
Modafinil is the better fit when your goal aligns with its mechanism (Inhibits dopamine reuptake via the dopamine transporter (DAT), increasing extracellular dopamine in the prefrontal cortex) and the dose range (100–200mg) suits your protocol. Half-life is 14h.
Choose Nicotine if
Nicotine is the better fit when your goal aligns with its mechanism (Agonist at nicotinic acetylcholine receptors (nAChR), particularly the α4β2 subtype in cortex and α7 in hippocampus) and the dose range (1–4mg) suits your protocol. Half-life is 2h.
