Marijuana dependence alters the brain’s response to drug paraphernalia

16 julio 2014

New research demonstrates that drug paraphernalia triggers the reward areas of the brain differently in dependent and non-dependent marijuana users. By letting users handle a marijuana pipe while in an fMRI, researchers found that areas of brain activation in the dependent users suggests a more emotional connection than in non-dependent users. Non-dependent users had greater activations in areas associated with memory and attention.
