Neuroactive drugs that affect the brain are known to use the removal mechanisms to their advantage. The dopamine system, noradrenaline system, serotonin system, and cholinergic system are the major neurotransmitter systems in the brain. Serotonin and norepinephrine are the main chemicals responsible for depression.

This field investigates both recreational drugs such as alcohol, caffeine, marijuana, cocaine, and LSD, and therapeutic drugs such as antidepressants and antipsychotics. Studies of the neural and psychological effects of drugs support the mind-brain identity theory over its chief rival, dualism, which claims that minds are distinct from bodies.
