Action stage.

Explanation:

Mathew, who is a marijuana addict, is looking to change that addiction and so decides to start surfing. This behavior by Mathew shows that he is embedded in Prochaska and DiClemente's trans-theoretical change model. This model arose with the aim of understanding how people change towards a certain addictive behavior.

Prochaska and DiClemente's transtheoretical model of change presents some stages. In Mathew's case, we can say that he is in the Action Stage.

The "action" stage is what people most often regard as the beginning stage of therapy. Here one engages in actions that will lead to a change, like Mathew who decided to start surfing as a way to replace marijuana.

The goal during this step is to produce a change in the problem you want to solve. The intention to change, however, does not guarantee that the change will continue over time.
