Early exposure to cannabis boosts young brains' sensitivity to cocaine, rodent study shows

A study made by Philippe Melas from Karolinska Institutet together with colleagues at Columbia University and the University of Cagliari in Italy published in PNAS shows that cannabis use makes young brains more sensitive to the first exposure to cocaine. By monitoring the brains of both adolescent and adult rats after giving them synthetic psychoactive cannabinoids followed by cocaine, the research team identified key molecular and epigenetic changes that occurred in the brains of the adolescents - but not adults.
