Final answer:
Slight intoxication can impair a person's capacity to enter into a contract as it may affect their ability to understand and comprehend the terms.
Step-by-step explanation:
Intoxication can have an effect on a person's capacity to enter into a contract. When a person is slightly intoxicated, their ability to understand and comprehend the terms of a contract may be impaired. This can lead to mistakes or misunderstandings in the agreement.
Additionally, in some cases, a contract entered into while intoxicated may be considered voidable if it can be shown that the intoxication prevented the person from fully understanding the consequences of their actions.
