What is meant by "tolerance" in addiction?

• A. Needing less of a substance to achieve the same effect
• B. Needing larger doses of a substance to achieve the same effect
• C. Experiencing withdrawal symptoms when not using the substance
• D. Having a psychological attachment to a substance

Answer: (B)

Tolerance in the context of addiction refers to the phenomenon where an individual requires larger doses of a substance to achieve the same effects that were once experienced with smaller amounts. This adaptation occurs because the body becomes accustomed to the presence of the drug, leading to reduced sensitivity to its effects over time. As a result, the individual must increase the dosage to attain the desired impact or sensation, which can exacerbate the cycle of dependency and addiction.

This concept highlights how prolonged substance use can alter both physiological and psychological responses, making recovery more complex. Understanding tolerance is crucial for treating addiction, as it can inform strategies for decreasing use or managing withdrawal symptoms, emphasizing the importance of careful dosing and monitoring during treatment.
