"My message to them is there is no hiding place, we will find you, we will catch you and we will put you behind bars."
Addict Amy Protheroe, 20, who has been an addict since she was 13 has just started her fifth treatment programme in Swansea.
She said: "When you're a heroin addict you wake up and you think straight away: "Where am I going to get money from, where am I going to score from?'"
"You get up, you go out, you get the money for the heroin, you buy the heroin, you do the heroin and then it starts all over again.
"To be honest, heroin has wrecked my life."
