The Polish anti-smoking artistic installation ‘Palę, bo...’ (I smoke because...) invited smokers to anonymously share the reasons for why they smoke. It had three editions. It first appeared in September 2016 at the ‘City of Stars’ festival in Żyrardów. In May of 2017, the project travelled to Wrocław, where it inaugurated the World No Tobacco Day conference entitled ‘Lung cancer can be prevented. Smoking is curable’ organized by the Health Promotion Foundation (Nadarzyn), the Medical University of Wroclaw and the Lower Silesia Center of Oncology. The exhibition remained there, at the Medical Science Information Center, for two months, before being transferred to its final destination at the Lower Silesia Center of Oncology in July 2017. In total, nearly 200 responses were collected.
