    What are the possible effects of smoking on the CNS and would this affect levels of neurotransmitters?

    Smoking increases blinking rate due to the nicotine being a stimulant increasing nerve transmission.

    nicotinic response improved (therefore improved cognitive function and memory retention - but otherwise not recommended)

    Nicotine is an artificial (by that I mean not naturally present in the human body) stimulant of nicotinic acetylcholine receptors. The receptors are found between nerves, and on muscles (peripheral nervous system), as well as in the central nervous system (the brain and spinal cord). It is a stimulant, so increases the rate of firing of that nerve. Since nerves in the CNS are usually inhibitory, nicotine can both increase and decrease "brain activity". It's also been linked to the stimulation of dopaminergic neurons, which activates the dopamine pathway. Dopamine is a reward pathway, and at least partially explains nicotine's addictiveness.
