Washington, July 8: A study of marijua and alcohol use in people between the ages of 18 and 24 has revealed that marijua users change over to alcohol at the age of 21. The study found a drastic increase in alcohol consumption in people just over 21, the minimum legal age to drink in many countries. At the same age, there was an equally dramatic drop in marijua use. “Alcohol appears to be a substitute for marijua. This sudden decrease in the use of marijua is because they suddenly have easy access to alcohol,” said Ben Crost, an economist at the University of Illinois. The authors used five years of data from the tiol Survey on Drug Use and Health. The participants were asked how many days in the past 30 that they had alcoholic drinks or used marijua. The study by Benjamin Crost and Santiago Guerrero was published in the Jourl of Health Economics. “Whenever there is a discontinuous threshold where something changes, it provides a way to identify a causal effect,” Crost said. “All of the costs and benefits from policies designed to reduce alcohol consumption, such as the minimum legal drinking age or liquor taxes, need to be assessed,” Cost added.
