Answer to Problem 1MM

Correct answer: After continued use of a psychoactive drug, the drug user needs to take larger doses to get the desired effect. This is referred to as tolerance.

Explanation of Solution

Tolerance is the diminishing effect with regular use of a particular dose of a specific drug. Thus, there is a need for the user to take larger and larger doses of that drug before understanding its effect. Psychoactive drugs produce more tolerance to achieve the desired effect. Addiction to a specific psychoactive drug promotes the drug users to create a desire for the drug and to use it continuously. With the continuous use of the drug develops tolerance as their brain chemistry accepts to equalize the effect of the drug.
