Amsterdam Underground is a cooperative. The guides are all owners and earn their income with their work. The guides often had to live as homeless and deal with the consequences of substance use. In these difficult circumstances they have developed knowledge and skills that they now use positively while guiding the city walks. Through their own experiences, the guides give an insight into the lives of people with a bit differently life path. The walk provides more understanding for (ex) addicts and fights the stigma that they experience on a daily basis. The work as a guide contributes to self-confidence, self-esteem and increasing self-reliance.
