Answer:
Step-by-step explanation:
Traditional quantitative genetics studies have revealed nicotine dependence is heritable and molecular genetics studies are providing increasing evidence that the genes responsible for nicotine's pharmacokinetics and pharmacodynamics are particularly important. These genes are responsible for how certain neurotransmitters are produced and metabolized, the number of receptors that are available to act on and how rapidly nicotine is metabolized by the individual. The more we understand these processes, the better the opportunity will be to formulate effective treatments.
