Dhruv has been consuming alcohol for many years. Recently he has joined an alcohol rehabilitation center. During his group therapy session, Dhruv shared the amount of alcohol he could drink to feel 'high'. He started with a peg and to get the same effect now he has to take greater amount. Identify the reason for this change:

Tolerance

The correct answer is Option (2) → Tolerance

Tolerance refers to a phenomenon where an individual requires a larger amount of a substance (in this case, alcohol) to achieve the same effect (feeling 'high') that they initially experienced with a smaller amount. This is a common characteristic of substance use disorders, where repeated use of alcohol leads to decreased sensitivity to its effects.

Why not the other options?

• Withdrawal: This refers to a range of symptoms that occur when a person reduces or stops using a substance they are dependent on, which does not apply to Dhruv's situation.
• Poor quality of alcohol: This could potentially affect the experience but is not the primary reason for the increased amount needed to achieve the same effect.
• Fixation: This term generally refers to an obsessive focus on a particular behavior or substance but does not specifically explain the need for increased alcohol consumption.
