Accurate estimate of drug exposure plays an important role in studies of the neurobiology of drug dependence. The validity of self-reported drug use by subjects participating in such studies has not been well established. This study examined the relationship between self-reported drug use and biological markers in 18 non-treatment-seeking cocaine-dependent individuals participating in research on the effects of cocaine on the brain. A significant relationship was found between self-reported frequency of cocaine use and hair cocaine concentration. Frequency of alcohol use correlated significantly with plasma carbohydrate-deficient transferrin and aspartate aminotransferase levels. These results suggest that self-reported substance use in non-treatment seeking research subjects is generally valid.

Peripheral nervous system complications such as acute demyelinating polyradiculopathy and mononeuropathy may rarely develop after substance use. A 27-year-old man used illegal drugs the day before his admission to the emergency service. Initially, he was suspected for rhabdomyolysis, due to elevated blood urea nitrogen, creatinine, aspartate aminotransferase, alanine aminotransferase, myoglobin, and creatine kinase levels. On Day 4, generalized edema and flask paralysis were noted in both upper limbs. The patient was diagnosed with bilateral brachial pan-plexopathy based on electrophysiological study results. He underwent a rehabilitation program. After eight months, repeated electrophysiological study revealed a significant improvement in all bilateral upper limb muscles, except for the right abductor pollicis brevis and abductor digiti minimi muscles. The underlying cause of bilateral brachial pan-plexopathy was rhabdomyolysis secondary to substance use. In conclusion, substance use in patients with non-traumatic plexopathy should always be questioned.
