A client currently prescribed a medication highly metabolized by the CYP 450 recently began smoking due to a stressful life event. True or False: The level of medication will increase in this client.

CYP 450 enzymes are responsible for the metabolism of many drugs. Smoking can induce certain CYP 450 enzymes, particularly CYP1A2, which leads to an increase in the metabolism of drugs that are substrates of this enzyme. When a person begins smoking, the induction of these enzymes can cause drugs to be metabolized more quickly, which typically results in lower drug levels in the body. However, the statement asks whether the level of medication will increase in this client, and since smoking induces enzyme activity, it would typically lead to decreased, not increased, drug levels. However, in the context of drug-drug interactions and other metabolic pathways, the metabolism rate could be altered in ways that might increase or affect the therapeutic response.
