How nicotine impacts the adolescent development of neural circuitry is not fully understood. Here authors show that early adolescent nicotine exposure in male mice blocked the maturation of nicotine-evoked dopamine signaling, causing an immature, vulnerable behavioral response in adult mice. Restoring their adult-like nicotine-evoked signaling unmasks a mature behavioral response in male mice.
