## Preliminary Evidence: The Impact of Contingency Management on Depression and Anxiety Among Crack Cocaine Dependent Patients in Brazil

Posted in Other

Recently an epidemic has occurred in São Paulo, Brazil’s largest city of over 11 million people, where in an inner city community known as “Crackloandia”, hundreds of people are openly using crack cocaine. The purpose of this research was to examine the effect of the treatment method known as contingency management (CM) paired with standard treatment (STCM) to see whether or not this treatment would alter depression and or anxiety in the population. It was hypothesized that CM would lessen the severity of anxiety and depression in the population while they received treatment for their crack cocaine use as a secondary, indirect effect. All data for the clinical trial was collected from 45 individuals seeking treatment for crack cocaine use disorder. This study found that CM effectively reduces depression and anxiety scores in patients who abuse crack cocaine. The implications of this research find it likely that CM is a treatment option capable of treating patients with a comorbidity of anxiety, depression, and substance abuse disorders.

## How to Look for Alien Life

The possibility of extraterrestrial life has been discussed for centuries, in both scientific and fictitious work. But it wasn’t until 1992 that the first exoplanet (planet outside of our solar system) was detected, and 2001 that the first exoplanet in a habitable zone was detected [1]. This makes exoplanetology and astrobiology relatively new fields of […]
