Cognitive Behavioural Therapy is based on the principle that our thoughts and behaviour affect our emotions, and that changing the way we think and act will change the way we feel.
More research has been conducted into effectiveness of CBT than most other therapeutic modalities, and the National Institute for Clinical Excellence (NICE) guidelines suggest to consider it for treatment of co-morbid anxiety and depression with clients who misuse cannabis or stimulants, and with opiate users who are stable or abstinent. CBT is also recommended for treatment of post-traumatic stress disorder which can be a significant factor in addictions.
