10.5Impairment

USPSA considers any substance, or circumstance, legal or otherwise which might impair or enhance performance, irrespective of route of administration, to be an extremely serious offense.

Any substance or circumstance that affects a competitor's ability to safely handle a firearm and participate in the sport must not be tolerated. Examples include but are not limited to prohibited substances (legal or otherwise), extreme lack of sleep, illness, various OTC medications taken for illness, some medical conditions, etc. Any person, who in the opinion of the Range Master, is visibly unable to safely handle a firearm, will be disqualified from the match and may be required to leave the range. This is not subject to appeal. Note: Violations of any host range rules that may have been broken at the same time are the responsibility of the host range and not of USPSA.
