Basis: Ecstasy is often seen as a non-addictive substance, which can cause dehydration and dangerous overheating of the human body. Despite the fact that these side effects are often described in literature, ecstasy remains one of the most popular illegal drugs used in the dance scene. Objective: The main aim of the research was to prove the effect of ecstasy (MDMA) on human thermoregulation and on the subsequent overheating of the organism. Meanwhile we demonstrate that thermal imaging can be used to measure statistically significant differences in temperature in respondents currently under the influence of ecstasy versus sober respondents. The secondary aim was to assess the effect of the amount of used ecstasy on the resulting temperature of the organism. Methodology: Thermal quantitative data were obtained as physical measurements by thermal imager. Next to that, additional information was collected in the form of a brief structured interview with respondents.

The aim of this work is to examine the influence of the menstrual cycle on craving for addictive substances and to try to map in what period of the menstrual cycle craving occurs most often for women. As a research qualitative design was used, semi-structured interviews with women in residential treatment of addiction (therapeutic community and psychiatric hospital) were used as a method. The research sample consisted of 13 respondents. Two semi-structured interviews were conducted two months apart. Data were analyzed using the tuft creation method. The results point at the existence of a relationship between menstrual cycle and substance craving. Even though the respondents' answers are ambivalent, the most common triggers of craving are unpleasant emotions that occur more frequently in the period before menstruation begins. However, less than half of the respondents report a direct link between craving and the period before menstruation. The findings are in...
