title: Effect of cocaine dependence on plasma phenylalanine and tyrosine levels and on urinary MHPG excretion.
abstract: Eight cocaine-dependent subjects had significantly lower urinary 3-methoxy-4-hydroxyphenylglycol excretion than did eight normal control subjects. Cocaine-dependent subjects also had lower plasma tyrosine levels but not to a statistically significant degree.
