ABC Laws

Which California state agency administers the Alcoholic Beverage Control Act and the Responsible Beverage Service (RBS) Training Program?

  1. ACalifornia Bureau of Security and Investigative Services (BSIS)
  2. BCalifornia Department of Alcoholic Beverage Control (ABC)Correct
  3. CCalifornia Department of Consumer Affairs (DCA)
  4. DCalifornia Department of Public Health (CDPH)

Why: The California Department of Alcoholic Beverage Control (ABC), created under Article XX §22 of the State Constitution and codified at Bus. & Prof. Code §23000 et seq., has exclusive authority to license and regulate the manufacture, sale, and service of alcoholic beverages in California, including administration of the RBS Training Program under AB 1221. CDPH (d) handles public health, DCA (c) oversees consumer professions, and BSIS (a) regulates security guards — none has jurisdiction over alcohol licensing.Cal. Bus. & Prof. Code §23000 et seq.

Alcohol Effects

Approximately what percentage of consumed alcohol is absorbed into the bloodstream through the small intestine, rather than the stomach?

  1. AAbout 20%
  2. BAbout 100% — the stomach absorbs none
  3. CAbout 80%Correct
  4. DAbout 50%

Why: Alcohol does not require digestion; it is absorbed directly through mucous membranes. Roughly 20% is absorbed across the stomach lining and about 80% across the small intestine, where the surface area is much greater. This is why food in the stomach (which slows gastric emptying into the intestine) slows absorption and lowers peak BAC, while drinking on an empty stomach speeds absorption. The stomach does absorb some alcohol (d is wrong); the intestine is the dominant site.RBS Training Curriculum; ABC Server Education
