Matt Willis bares all in addiction documentary – where to find help

Mat Willis has bravely opened up about his drink and drug addiction struggles and recovery journey in a new BBC documentary.

The Busted star and TV presenter, 40, said at one point he was doing six grams of cocaine on his own every day, while his wife, Emma Willis, said she was "so scared he would die", sparking an emotional response from viewers.

Having relapsed once before, Fighting Addiction also explores what it's like to be in what Matt describes as a "constant state of recovery".

Following other celebrities opening up on their addiction experiences, including Tony Adams and Cara Delevingne, more is being done to help break the stigma and encourage others to get the help they need.

Here we outline how addictions might present in people and where to get help.

What is addiction?

Addiction is when you have no control over doing, taking or using something to the point where it could be harmful to you, according to the NHS.

Addiction is commonly associated with drugs, alcohol, gambling and smoking in this way, but you can be addicted to anything.

This may also include:

• Work – you may become physically exhausted, your relationship, family and social life might be affected, or you never take holidays

• Internet – you may spend hours each day and night surfing the internet or gaming while neglecting other aspects of your life

• Shopping – you may buy things you don't need or want to achieve a 'buzz', followed by feelings of guilt, shame or despair

Addiction causes

There are many reasons why addictions may begin. Drugs, alcohol and nicotine, for example, can have a powerful effect on the brain, creating a feeling that you may have the strong urge to experience again.

Gambling, if successful, can give you a similar 'high', which can lead you to want to try again until it becomes a habit.

If you are addicted to something, you can have withdrawal symptoms or a 'come down' without it, meaning some may keep doing it to avoid these unpleasant feelings, becoming a vicious cycle.

Addiction can get out of control when you are both dependent on something and need (or need to do) more and more of it to achieve the same sensation.

Research also associates some addictions, like alcoholism, may have a family history, as well as environmental factors. They can, however, happen to anyone.

Signs of addiction

'Managing' an addiction can put a big strain on your work life and relationships. When your addiction is substance abuse, this can have serious psychological and physical effects on you.

Behavioural and social signs, include:
