Step-by-step explanation:
I disagree with the part of the statement that says "those who smoke cannot be thinking about costs and benefits" because although the phrase is correct in the logical and scientific context about the harm of smoking, it is also correct to state that the statement is liable to different interpretations according to each individual.
Therefore, I do not agree with this statement due to the fact that each person has a different concept of benefits and costs, for an individual to smoke, even though it is harmful to health, it is compensable for the sensation of pleasure it causes.
