Amendments to the Polish anti-tobacco Act implemented on the timeline gradually introduce increased protection for persons under 18 years of age. These changes, introduced under the influence of international and EU law, extend the scope of the ban on selling nicotine products to youth, and introduce other related obligations (verification and information obligations). The study objective was to assess effectiveness of provisions. Legal analysis and survey on violations was performed. Despite the positive legislative trend, the current state of the regulation cannot be considered optimal. Presented research indicates the direction of further legal changes in the scope of limiting the provision of nicotine products to persons under 18 years of age, which would contribute to making the Polish regulation more effective, in line with global trends in the fight against nicotine addiction.
