A recent study published in the Human Brain Mapping journal shed some light as to why long-term cannabis consumers crave the herb. “Now that we have identified there are differences in large-scale brain network patterns in long-term cannabis users when there is craving, we can use these as biomarkers of cannabis use disorder to aid treatment strategies. Further studies are needed to determine how these brain network patterns might change over the course of treatment and recovery,” explains Dr. Francesca Filbey, PhD, director and professor of cognitive neuroscience.
