Brain-derived neurotrophic factor (BDNF) Val66Met genotype has been associated with neurobehavioral deficits. To examine its relevance for addiction, we examined BDNF genotype differences in drug–seeking behavior. Heroin-dependent volunteers (N=128) completed an interview that assessed past-month naturalistic drug seeking/use behaviors. In African Americans (N=74), the Met allele was uncommon (carrier frequency 6.8%); thus, analyses focused on European Americans (N=54), in whom the Met allele was common (carrier frequency 37.0%). In their natural setting, Met carriers (n=20) reported more time– and cost–intensive heroin–seeking and more cigarette use than Val homozygotes (n=34). BDNF Val66Met genotype predicted 18.4% of variance in ‘weekly heroin investment’ (purchasing time × amount × frequency). These data suggest the BDNF Met allele may confer a ‘preferred drug–invested’ phenotype, resistant to moderating effects of higher drug prices and non-drug reinforcement. These preliminary hypothesis-generating findings require replication, but are consistent with preclinical data that demonstrate neurotrophic influence in drug reinforcement. Whether this genotype is relevant to other abused substances besides opioids or nicotine, or treatment response, remains to be determined.
