Briefly describe the development of cross-tolerance in chronic drinkers due to alcohol consumption
Over time, chronic alcohol consumption can activate a group of liver enzymes that assist in alcohol metabolism, reducing the amount of time a person remains intoxicated. This is why some chronic drinkers develop a tolerance to alcohol, reducing its effects and allowing them to drink excessive amounts before becoming intoxicated. Because these enzymes also aid in the metabolism of other drugs, a heavy drinker may develop a cross-tolerance to these substances as well. In other words, when tolerance to alcohol develops, it is possible to become more tolerant (less responsive) to certain other drugs.
