Explanation:
Depending on the institution, substance-abuse treatments may vary in regard to duration and phases. Generally, treatments for substance abuse consist of four phases:
- Initiation: This first stage focuses on providing helpful information to the person/patient about all treatments and options. <u>During this phase, the person goes through a process of </u><u>detoxification</u><u>, that is, preventing them from using the drug to remove their dependence.</u>
- Abstinence - first phase: This stage is one of the most difficult ones as the person usually exhibits a variety of emotions associated with depression, sadness, anxiety because of the withdrawal of the drug. <u>During this phase, they received psychological help to prevent any relapse and to </u><u>become more stable</u><u>, that is, to </u><u>control drug cravings.</u>
- Abstinence - second phase: This stage is focused on<u> maintaining abstinence and stability</u>. In conjunction with the second phase, this is also difficult but rewarding. The person receives behavioral therapy so he/she can acknowledge how the drug intake resulted in numerous issues and, in contrast, stopping its use can change her/his life in a diversity of positive ways.
- Aftercare: This stage focuses on long-term goals and, through therapy and counselling, <u>helps the person to </u><u>obtain education, find a job</u><u>, and </u><u>continue their stability and abstinence.</u>
