Validation of a Remote Wireless Sensor Network (WSN) Approach to the Individualized Detection of Cocaine Use in Humans
Completed · Phase 1
Conditions studied: Cocaine Dependence
In brief
This study looks to explore the feasibility, sensitivity, validity, and specificity of a Remote Wireless Sensor Network (RWSN) approach to the detection of cocaine use/intoxication in the inpatient human laboratory, as well as in the outpatient setting ("real world"). Lastly, we look to design an algorithm for reliably detecting cocaine use in real-world settings and inference techniques for understanding the relationship between cocaine use and user contexts.

You may qualify if…
- age 18 - 50 years,
- voluntary, written, informed consent,
- physically healthy by medical history, physical, neurological, ECG, and laboratory examinations,
- DSM-IV criteria for Cocaine Abuse (305.60) or Cocaine Dependence (304.20)
- recent street cocaine use in excess of amounts to be administered in the current study,

- < 1 year of cocaine dependence,
- a primary major DSM-IV psychiatric diagnosis (schizophrenia, bipolar disorder, etc.), unrelated to cocaine,
- a history of significant medical (cardiovascular) or neurological illness, ie prior myocardial infarction, current active symptoms of cardiovascular disease / angina, evidence of cocaine-related cardiovascular symptoms, prior arrhythmias or need for cardiov ascular resuscitation, neurovascular events such as transient ischemic attacks, stroke, and/or seizures Parameters re: elevations in vital signs are now explicitly specified under "Safety features built into our one-day self-administration paradigm).
- current use of psychotropic and/or potentially psychoactive prescription medication,
- seeking treatment for drug abuse/dependence (for experimental cocaine component),
- physical or laboratory (β-HCG) evidence of pregnancy.
- current use of any medication (prescription or over-the-counter) determined to cause potential drug interactions by the study physicians.
