Smoking causes depression because of the withdrawal from a physically and psychologically addictive substance, called nicotine. Nicotine which acts as a receptor for the neurotransmitter, acetylcholine, indirectly stimulates the release of another neurotransmitter, dopamine, in the brainâs reward or motivation center.
As the body adjusts to less caffeine, these symptoms should subside. Nicotine May Cause Less Sleep. Nicotine is also a stimulant, and nicotine side effects can cause insomnia and withdrawal symptoms similar to caffeine. Smoking may also create other sleep disturbances.
