What does Texas HB166 do?
HB166 amends the Texas Penal Code to establish a legal presumption of felony endangerment if Fentanyl (Penalty Group 1-B) is possessed, manufactured, or introduced in the presence of a child, elderly, or disabled individual. This legislation effectively shifts the evidentiary burden onto care providers, childcare facilities, and senior living communities to prove they did not endanger a vulnerable individual if Fentanyl is discovered on the premises. Implementation Timeline Effective Date: May 24, 2025 (Note: Due to 2/3 supermajority passage, this supersedes the standard September 1 date).
