Answer:
c. Tolerance
Step-by-step explanation:
In psychology the term tolerance is used in substance use to refer to what occurs when the person doesn't respond to the substance the way he/she initially did, in other words, it takes larger doses of the substance to have the required effect or the same effect it used to have at first.
In this example, Tayla first needed just a few inhalations to cloud her mind. Now she needs to smoke more and more to achieve the same effect. We can see that she is not responding to marijuana the way she used to and now she requires more inhalations to have the same effect. Therefore this is an example of tolerance.
