Relating to: the membership of the Controlled Substances Board.

AB 273 amends Wisconsin statute 15.405(5g) to update the membership of the Controlled Substances Board. It adds the secretary of agriculture, trade and consumer protection (or their designee), chairpersons of several medical boards (pharmacy, medical, physician assistant, dentistry, nursing), and two appointed experts (a psychiatrist and pharmacologist) serving 3-year terms. The bill does not change the board's duties but specifies who serves on it. This directly affects the composition of the board, which reviews controlled substances regulations. The change is procedural, focusing on board structure rather than policy.
