Controlled Substances - As enacted, enacts the "Ben Kredich Act," which, for the purpose of proving a person violated state law relative to driving under the influence of an intoxicant, establishes that evidence that the person was suspected to be impaired secondary to the sedative or otherwise intoxicating effects of a controlled substance, and was administered within 24 hours prior to the alleged violation, an opioid antagonist for an opioid-related overdose, creates a presumption that the defendant's ability to drive was sufficiently impaired by the substance that caused the opioid-related overdose to constitute a violation of state law, and authorizes a first responder who administers an opioid antagonist to an individual experiencing an opioid-related overdose to provide information on the risks associated with driving for a 24-hour period following administration. - Amends TCA Title 39; Title 40 and Title 55.
