FIELD NOTE / 01

Nicotine is addictive

Nicotine can create dependence. The product format changes the route of exposure; it does not remove the addictive substance.

No nicotine product is risk-free.

Nicotine is addictive: NICOTINE; DEPENDENCE RISK
No nicotine product is risk-free.

FIELD NOTE / 02

Route matters

A pouch releases nicotine in the mouth; cigarette smoke is inhaled. These are different exposure routes, and a product comparison needs more than a slogan about smoke or vapour.

Different mechanism is not proven benefit.

Route matters: DELIVERY FORMAT; ABSORPTION ROUTE
Different mechanism is not proven benefit.

FIELD NOTE / 03

Evidence has limits

The NHS says nicotine pouches are not licensed stop-smoking products in the UK, and that evidence on their short- and long-term safety and cessation effectiveness remains insufficient.

Do not present KROSSA as a quit aid.

FIELD NOTE / 04

When to seek advice

Read contraindications and stop use if adverse effects occur. A healthcare professional can answer personal medical questions; a brand article cannot decide suitability for an individual.

Personal risk needs professional advice.
