The film "One Gram of Life" will be shown free on Thursday, 19 November, at 6pm at the Prosveta 1888 community centre in Pomorie, the organisers said. It is based on real events and runs for three hours.

The film is part of a national initiative of the same name, created by Mariela Kirova and Malin Taushanov. The organisers say its aim is to protect children's future and save as many young lives as possible.

Atanas Mihaylov directed the film and Emilian Dechev was behind the camera. The cast includes Ivaylo Zahariev, Kaloyan M. Paterkov, Tervel Pulev, Dobi Glavincheva, Simona Yordanova, Pavel Dimchev, Leo Panov and Alexander Vezenkov.

Four lives intertwine in one story about drugs. Its themes are the will to survive, broken dreams, naivety, anger, pain, friendship and conflict. The film looks at relations between children and parents, and at the personal, family and social harm drugs do to young people.

The makers say the real problem is widespread drug use by children.

The organisers say people turn to drugs for different reasons, but all of them lead to an abyss that is hard to climb out of, and often impossible. They call on people "to choose life", because every choice matters.
