Surprisingly for a UK show, handguns are often shown. However, they are seldom fired.

The violence in this show is seldom very graphic. Blood is fairly rare.

In series 2 episode 1, a man is nearly suffocated by a man who tries to kill him with a plastic bag

The entire premise of this show revolves around drug dealers and drug gangs.

One of the main characters has a chronic drug addiction, and is often seen snorting cocaine and smoking weed.

One of the main characters' mothers is a heroin addict, who is seen shooting up.

There are a lot of intense scenes. In most episodes, a gun is put to someone's head.
