Just like repeated use of alcohol, repeated or continuous use of substances (drugs) which are addictive such as cannabis, opioids, sedatives, inhalants also need treatment. These substances not only lead to addiction but also cause mental and physical problems. Some of these substances are associated with psychiatric problems such as psychotic disorder, sleep disorders, delirium, anxietydisorder, bipolar disorder and obsessive compulsive disorder among other problems. Early intervention, in such cases, helps prevent suffering.
