The purpose of the study is to explore how the COVID-19 situation has affected the illegal retail market and drug use patterns. Three research questions were formulated: 1) What has been the COVID-19 impact on the retail illegal drugs market. 2) How has the pandemic impacted drug use patterns. 3) Are there trends that presumably would have an impact after COVID-19. https://megavitamines.shop/product-category/childrens-magnesium/
