Substance abuse is an coping mechanism.

Substance abuse is a mechanism for coping with emotional and social problems.

Explanation:

Many people start using abusive amounts to escape their emotional and social problems. Even though these substances temporarily promote false relief in people's problems because for a period of time, they forget that their problems exist.

For this reason, we can say that many people abuse substance as a way of coping with emotional and social problems. However, it should be noted that the use of these substances is not a healthy coping strategy because in addition to causing damage to the body, provides palliative solutions and failures, which are likely to worsen the individual's problems.
