Questions: Repeated uses of stimulants such as Meth can deplete important neurotransmitters like the following except: (A) dopamine (B) norepinephrine (C) GABA (D) serotonin

The answer is (C): GABA.

Explanation for each option:

(A) Dopamine: Methamphetamine use significantly increases the release of dopamine in the brain, which can lead to the depletion of this neurotransmitter over time. This is correct.

(B) Norepinephrine: Methamphetamine also increases the release of norepinephrine, which can similarly become depleted with repeated use. This is correct.

(C) GABA: Gamma-Aminobutyric Acid (GABA) is primarily an inhibitory neurotransmitter, and while stimulants like methamphetamine affect the balance of excitatory and inhibitory neurotransmitters, GABA is not typically depleted by methamphetamine use. This is incorrect.

(D) Serotonin: Methamphetamine can also affect serotonin levels, leading to their depletion with repeated use. This is correct.

Summary: Repeated uses of stimulants such as Meth can deplete important neurotransmitters like dopamine, norepinephrine, and serotonin, but not GABA. Therefore, the correct answer is (C): GABA.
