Among Amsterdam’s central canal rings you can find our physical smartshop; When Nature Calls. Since we opened in 1998 our team has always been made up of passionate and diverse individuals who are well educated to have a deep understanding of not only our Amsterdam psilocybin Truffles but also of our entire product range. Our approach centers around holistic wellness, with a carefully selected product range of only the highest quality products to boost psychological, neurological, physical, and spiritual health. We endeavor to assist each client in selecting the products for their unique needs, from therapeutic journeys, those who need help sleeping, those in pain, or those looking for a recreational experience.
