In Nepal for decades, many children have left their villages in the hope of a better future in the city, but many of them have become street kids, begging, prostituting themselves and collecting plastic to survive. These street children (Kathey in Nepalese) live permanently on the streets, keeping little contact with their families, due to  complex situations, parents' alcoholism, illness, extreme poverty, high number of children, death of a parent or remarriage. They find in their band what their family cannot bring to them, the feeling of belonging to a group, to a family, the mutual attachment, the helping hand. Because of their young ages, they are exposed to all forms of exploitation, trafficking, accidents, violence, crime, gang warfare are common on the street. Most of them take drugs to forget the hunger, the cold. The youngest (from 6-7 years) sniff glue, commonly called dendrite, which contains toluene, a chemical that causes hallucinations and destroys brain cells. This drug, however forbidden, is sold in drugstores for 250 rupees the 100gr (1.90 euros). When they reach adolescence, half of them take Brown Sugar or more often morphine or methadone (opioid) for about 1000 rupees per injection. The Katheys live in small gangs, following their own rules, making them feel "free".. Marginalized by society, they create their own system. In 2016, the number of street children was estimated at 5,000, with the majority being in Kathmandu, the government then implemented the "no children on the street" program with the implementation of a direct line #104 that allows to warn the presence of a gang of young people, they are  "rescued" (in the words of the Child Protection Bureau, CCWB) or "arrested" (according to those of the kids) by the police, then they are taken to NGOs or more often to rehabilitation center. But most children can not adapt to the strict authority of the rehab that limits their freedom, the majority of them have already passed in it a dozen times. According to their testimonies, NGOs and detox center are not controlled, in many of them, they suffer psychological or physical torture, so they feel these passages as  punishment or as prison sentence. It is estimated that only 40% of children are released from the street and permanently detoxify. This law is only applied in Kathmandu, and only for the youngest, adolescents still live in makeshift camps on vacant land, alternating between prison, detox center and periods of "freedom".
