A teen resident of the Portage drug rehabilitation centre on the West Island praises the treatment program that turned his life around, but he's worried about the centre's uncertain future.

The 18-year-old says marijuana was taking over his life before Portage.

"It was a way for me to escape and stay high all day and not deal with what goes on in the house and not deal with parents," he told CBC's Daybreak.

He says his parents' marriage was marred by violence and after they separated, he ended up living in a shelter with his mom and his younger sister. 

But Portage's future on the West Island is in limbo. The Batshaw Youth and Family centre, which also helps troubled teens, owns the property and needs it for its own expansion.
