Bupropion and Nicotine, a caution.
Bupropion and nicotine replacement have been intentionally combined for smoking cessation, and the combination can improve quit rates for some people. The same combination can also increase insomnia, headache, jitteriness, palpitations, and blood pressure concerns, especially if nicotine is used heavily through vaping, pouches, or multiple replacement products. Bupropion also lowers seizure threshold, so excess stimulant-like exposure matters.

Caution
What is happening. Bupropion and nicotine replacement have been intentionally combined for smoking cessation, and the combination can improve quit rates for some people. The same combination can also increase insomnia, headache, jitteriness, palpitations, and blood pressure concerns, especially if nicotine is used heavily through vaping, pouches, or multiple replacement products. Bupropion also lowers seizure threshold, so excess stimulant-like exposure matters.
Mechanism. Bupropion inhibits norepinephrine and dopamine reuptake and antagonizes nicotinic acetylcholine receptors. Nicotine activates nicotinic receptors and increases sympathetic catecholamine release, so the combination can support cessation while adding autonomic and neurostimulant adverse-effect burden.
Recommendation. Use nicotine with bupropion only as part of a planned cessation strategy or with your clinician's knowledge. Check blood pressure and pulse if you use nicotine frequently or develop headaches, palpitations, anxiety, or chest tightness. Seek urgent care for chest pain, fainting, severe shortness of breath, seizure, or a new irregular heartbeat.
