College-age kids are drinking less alcohol – but smoking more marijuana


November 19, 2020

Young adults aren’t drinking as much as they used to. In fact, more than a quarter don’t drink alcohol at all, recent surveys show.

It’s good news for health. But there is also a downside in the data: While alcohol use is falling among 18-to-22-year-olds, marijuana use is inching upward. The number of young adults using both alcohol and marijuana is also rising, heightening concerns about a future surge in substance abuse problems, new research shows.

I am a professor of psychology at Texas State University who has been studying young adult and adolescent substance use for over 15 years. A key interest of mine is how substance use changes over adolescence and young adulthood. It is a period of profound change: A 13-year-old is very different from a 25-year-old in nearly every way.

With colleagues at the University of Michigan, the University of Central Florida and Iowa State University, I have been investigating trends in alcohol and marijuana use in young adults to better understand how use changes with age. The latest numbers offer both hope and concern.

Gen Z is breaking stereotypes

There are reasons for the stereotype of hard-drinking, substance-using young adults, as photos and videos from bars and college parties will attest. But surveys and our analysis suggest that binge drinking isn’t as common as people may believe it is.

Using data from the annual National Survey on Drug Use and Health, we found that in 2018 nearly 30% of college-age adults, ages 18-22, had not had a single alcoholic drink during the previous year, compared with fewer than a quarter in 2002. Over 60% had not used marijuana at all.

Among 18-to-25-year-olds, the number who reported binge drinking in the previous year fell from 39% in 2015 to 34% in 2019. That may be influenced at least in part by beliefs that are forming in high school. Another survey shows that nearly three-quarters of high school seniors think their friends would disapprove of weekend binge drinking, up from just over half in the early 1980s.

Adolescents – typically 12 to 17 years of age – were more likely to avoid both alcohol and marijuana than they were two decades ago, part of a larger trend in declining substance use and risky behavior among adolescents seen in a variety of national surveys and data sources. In 2019, nearly 80% of adolescents had not used alcohol at all in the previous year, compared with 65% in 2002, and 87% had not used marijuana.

Using both marijuana and alcohol

The bad news is that the number of college-age young adults saying they used marijuana at least once in the previous year has increased, from 33% to 37%.

The vast majority who said they used marijuana also used alcohol. We found that the increase in young adults using both was a result of young adults who used alcohol taking up marijuana, too.

This increase in using both alcohol and marijuana is an important warning sign, because young adults in that group also had much higher rates of other illicit drug use, like cocaine, and prescription drug misuse, involving medications like opioids or benzodiazepines.

That may signal that a greater number will need substance use treatment in the coming years.

Why the changes?

One theory for the shifting trends in alcohol and marijuana use is that adolescent substance use is now starting at later ages.

The data support this: The numbers of adolescents starting alcohol use has declined somewhat, while more college-age adults are first-time alcohol and marijuana users. Why that shift is occurring is less clear, but one theory is that adolescents have been engaging in more virtual contact than face-to-face contact in recent years and they rarely use substances when they’re alone.

Changing regulations likely also play a role. Marijuana is now legal for medical or recreational use in an increasing number of states.

Attitudes toward alcohol and marijuana have also changed over the years, particularly for marijuana.

The Monitoring the Future study, which has tracked substance use in adolescents and young adults since 1975, indicates both a sharp decline in disapproval of marijuana among middle and high school students and a decline in how harmful they perceive marijuana to be. In fact, more young people in that age group now see more harm from regular alcohol use than disapprove of marijuana.

How the pandemic will change young people’s habits with alcohol and marijuana isn’t yet clear. One survey conducted this spring when many restaurants and bars were closed found that adults over 30 were drinking alcohol 14% more often. However, when researchers in Australia homed in on younger adults in Gen Z, they found a different story: Older age groups may be drinking more, but with bars and restaurants closed, 44% of the college-age crowd reported drinking less.


Campaign launched to ban all alcohol advertising in Scotland

A CAMPAIGN group has urged every candidate in next year’s Holyrood election to support a “total ban” on alcohol advertising.

In its manifesto ahead of the vote in May, Scottish Health Action on Alcohol Problems (SHAAP) is pushing for parties to support four “focus areas” aimed at reducing alcohol-related harms.

They have asked for a reduction in the affordability, availability and attractiveness of alcohol, which includes restrictions on advertising, promotions and sponsorship, as well as a review of minimum unit pricing with the possibility of raising the current 50p rate.

Minimum unit pricing came into effect in 2018 after years of legal wrangling.

Sales in off-licences and supermarkets dropped by between 4% and 5% in the year after its introduction, according to a study by Public Health Scotland earlier this year.

SHAAP also said regulations should be created on sales, creating alcohol-only shops and removing drinks from supermarkets, adding government control of alcohol sales should be “seriously explored”.

Investing in treatment, reducing health inequalities and protecting young people are other key areas the group – which is a partnership between the Medical Royal Colleges in Scotland and the Faculty of Public Health – is hoping will garner support from prospective MSPs and their parties.

The manifesto says: “Scotland is an international leader in advancing evidence-based alcohol policies that protect people’s health.

“Yet despite the commitments and achievements of the 2009 and 2018 alcohol frameworks, levels of alcohol harm in Scotland remain high.”

It adds: “The Covid-19 pandemic has transformed life in Scotland since March 2020.

“For alcohol, the pandemic has accelerated the long-standing trend towards home drinking, which involves additional potential risks.

“So far, research indicates that the heavier drinkers have increased their consumption.”

SHAAP chairman Dr Peter Rice said: “Covid-19 has shone a light on the patchy and often disjointed nature of alcohol treatment service provision, even prior to lockdown, and we do not yet know what long-term impact the pandemic will have on people’s drinking behaviours, though research so far indicates that heavier drinkers have increased their consumption.

“Our 2021 manifesto highlights cost-effective, evidence-based policies that, if properly implemented, will work to ensure that Covid-19 does not exacerbate alcohol-related harm and health inequalities in Scotland and that we are able to meet long-term public health goals that are essential if we are to build a healthier, fairer future.”

Statistics published this week by Public Health Scotland showed a slight drop in alcohol-related hospital admissions between 2019-20 and the previous year, with 23,685 people admitted a total of 35,781 times.

Scottish Labour health spokeswoman Monica Lennon described the statistics as proof of a “ticking health time bomb” in Scotland.
