Sassafras was banned when they found out that safrole caused liver cancer. Caramel.coloring, commonly used as a coloring and flavoring agent in soda like Coca Cola, in alcohol, and in baked goods, has been know to be a carcinogenic cytotoxin for years and is still legal. I have seen warning labels regarding E150 on drinks abroad.Does it still contain Sassafras? My favorite from back in the day was Hi-Q root beer in bottle. Had the A&W stand too.
