Home manufactured methamphetamine known as 'Pervitin' has historically dominated the drug market in the Czech and Slovak Republics. Seizures and surveillance data indicate some displacement of 'Pervitin' across Europe to areas of low reported prevalence (Nordic countries, Germany, Cyprus, Greece and Portugal). We present the first single case study of clandestine production of 'Pervitin' to Ireland, a country with low reporting history of methamphetamine. Content analysis yielded three descriptive themes; 'Pervitin' use, Decisions to Use and Effects; Legality and Hazards; and 'Clandestine Manufacture.' The study yielded unique insight into migration of this culturally specific drug, and how continued cultural contexts for use and 'cooking' remain intact when residing in the host country. Given its unique cultural nature and national characteristics, continued migration of Eastern European citizens across Europe, diffusion of clandestine production warrants continued surveillance. Appropriate service responses require culturally appropriate information and outreach services to Eastern European service users.
