The central difference is combustion

A cigarette delivers nicotine together with smoke from burning tobacco and paper. NRT separates nicotine from that combustion mixture.

[1][2]

Delivery speed and pattern differ

A patch releases nicotine slowly; oral or spray products act more quickly. Cigarettes reach the brain rapidly, which contributes to their reinforcing effect.

Medicine still has instructions

Using a product correctly, understanding side effects and checking suitability matter. General evidence of benefit is not a personal prescription.

What to keep in mind

  • NRT and cigarette smoke are not equivalent exposures.
  • Different NRT forms have different delivery profiles.
  • Product choice and dosing belong with the label and a qualified professional.

Common questions

Does NRT contain tar or carbon monoxide?

No. Those are products of combustion, and NRT does not burn tobacco.

Can I combine different forms?

Combination approaches are used in guidance, but individual suitability and instructions should be checked with a clinician or pharmacist.
