ANC traces the Mumbai drug route from source to suburb

Ganja
It is cultivated in districts of Gadchiroli, Yavatmal, Dhulia, Beed, Osmanabad in Maharashtra, some of which are Naxalite affected. Ganja is also trafficked into Mumbai from the Andhra-Odisha border and Chhattisgarh.

Charas
It is cultivated illegally in states of Jammu and Kashmir and Himachal Pradesh. The traffickers, says the ANC, adopt rail/road route from J&K, Himachal Pradesh to Mumbai with Delhi as a transit point. A recent modus operandi is that charas couriers traffic Nepali charas to Gulf countries from Mumbai and return with smuggled gold or cigarettes.
