joja [24]

Answer:

True

Explanation:

Tobacco is consumed during smoking which contains an addictive substance called Nicotine. Nicotine exerts its effect on the body by stimulating the acetylcholine receptors in the neurons. The stimulation of these receptors stimulates another neurotransmitter like glutamate, dopamine and GABA which produce addictive effects in humans.

Since the acetylcholine is involved in stimulating the other neurotransmitters therefore true is the correct answer.

Thus, true is the correct answer.
