If there is no underlying medical condition or disability, what is a likely sign of intoxication?

diminished emotions
increased perspiration
reduced drowsiness
intensified perception
?

Explanation:

diminished emotions

increased perspiration

reduced drowsiness

intensified perception

the fourth amendment protects:

"the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."  

so this would mean the denial to search and seizure without warrant or permission.
