Drinking Alcohol or Marijuana (Pot) Use: Which Choice?

Does price influence decisions about drinking alcohol or marijuana use? That is, do differing prices or availability of alcohol influence the use of marijuana?


drinking alcohol or using marijuanaEconomists note that some products can be used to replace one another. In such cases, as the price of one goes up, its use drops. At the same time, use of the other less expensive product increases. Or if one becomes less available, its use drops. And use of the more available product rises. In short, one becomes replaced for the other.

Unintended Consequence

Two economists compared the self-reported drinking and use of drugs. It was just before and just after the twenty-first birthday. They found that pot use dropped by about 10%. That’s when people reached the legal age for drinking.

The authors suggest one of the unintended results of the age 21 minimum legal drinking age. It pushes young people into drug use.

Advantages of Marijuana

Pot may also be preferred because it is less likely to be detected than alcohol. An example is that of drug counselor and recovering addict, Allison Whitney. She says that she got into several crashes as a teenager because of smoking pot while driving. Police would pull her over for erratic driving. They always let her go. That’s because she passed breath tests.

Ms. Whitney says pot is attractive to teens for several reasons. First, it’s easier to hide than alcohol. Second, a person can get high faster than they can get intoxicated. Third, parents don’t detect pot. Fourth, nation-wide research has found it easier for young people to buy pot than beer. That’s because of increased enforcement of laws against the sale of alcohol to those under 21.

Restricting availability of alcohol to those under the age of 21 may have made pot a more attractive. So reducing alcohol availability even more might increase pot use.

One alternative is to promote harm reduction to reduce the effects of alcohol abuse. And that’s among people of any age.
