Although substance use and abuse can occur in adolescence, young adulthood, middle age, or old age, it can look different at these various life stages. Young adults, for example, don’t have the same patterns of use as their grandparents’ generation. Being aware of the trends in substance use among young adults can help you know how to help the young adult in your life who is showing signs of developing a substance use disorder.
Increased Dangers to Young People
Although substance use occurs across age groups, Psychology Today points out that it can be particularly detrimental to adults under the age of 25, for five main reasons:
- Effects on the brain – The human brain continues growing and developing into a person’s early twenties. Introducing alcohol, nicotine, and other drugs can keep the most elaborate and advanced parts of the brain from developing properly.
- Heightened addiction risk – An adolescent brain craves adventure and new experiences, so teens and young adults are more likely to overindulge. Also, substances may interfere with the brain’s development of decision-making ability, will power, reasoning, and planning. If these parts of the brain don’t form correctly, addiction is more likely to occur.
- Long-term health risks – The earlier a person starts using substances and the heavier their use, the more abuse their bodies are taking and the more likely they are to develop conditions like heart disease, cancer, and dementia.
- Behavioral health risks – Substance abuse can exacerbate existing mental health needs and create new ones.
- Social development delays – If a person has only learned to make friends in a context of sharing alcohol or another drug, they may struggle to build relationships in any other setting.
Tracking the Trends
The “Monitoring the Future” Survey is one way we can learn about trends in substance use in young adults and among adolescents. This tool monitors the trends in drug use among 8th, 10th and 12th graders, as well as college students and young adults based on self-reports. The most recent edition, published in 2018, shows changes over time in the types of drugs used and the specific age groups that use them.
Alcohol is more commonly used among young adults than any of the other drugs on the survey.
In 2018 alcohol had been previously tried by:
- 23.5 percent of 8th graders
- 43 percent of 10th graders
- 58.5 percent of 12th graders
- 77.4 percent of college students
- 85 percent of young adults
While these numbers may be concerning, it should be noted that they have decreased significantly since 1991, the first year data was collected. In 1991, for example, 70.1 percent of 8th graders and 83.8 percent of 10th graders reported drinking alcohol.
- Unintentional injuries (car accidents, falls, burns, alcohol poisoning, etc.)
- Violence (homicide, suicide, intimate partner violence, and sexual assault)
- Sexually transmitted diseases (STDs)
- Unintended pregnancy and poor pregnancy outcomes (miscarriage and stillbirth)
- Memory and learning problems
- Alcohol dependence
The next most commonly used drug in this age group was marijuana. A new trend in marijuana use is vaping it in an electronic cigarette. This was tracked separately in the survey. The percentages of young people having used marijuana as of 2018 is as follows:
- 13.9 percent of 8th graders
- 32.6 percent of 10th graders
- 43.6 percent of 12th graders
- 52.4 percent of college students
- 60.1 percent of young adults
Between 1991 and 2018, the number of 8th and 10th graders using marijuana rose 3.7 percent and 9.2 percent respectively. The other age groups measured also saw increased marijuana use.
While young people did report other substance use, the percentages of lifetime use were largely in single digits for the other drugs on the survey. Only hallucinogens, amphetamines, and narcotics as entire groups, not individual drugs, surpassed 10 percent of survey participants having tried them, and most did not do so until they reached college or young adulthood. Over time, there was a decrease in young adults using hallucinogens and sedatives, but an increase in narcotics.
According to the Centers for Disease Control (CDC), the factors that make a young person more likely than their peers to engage in substance use include:
- Substance use among other family members (including parents)
- Parents endorsing substance use
- Parents not engaged with the child
- Sexual orientation or gender identity rejected by family
- Substance use within friend group
- Disconnected from school
- Poor school performance
- Sexual abuse in childhood
- Untreated mental health needs
Parents who closely monitor the behavior of their children, who communicate disapproval of substance use, who live a substance-free life, and who are able to find effective mental health treatment for their children are less likely to have children who use substances.
Young people who feel connected at school, whose friends don’t use alcohol or other drugs, and who’ve never experienced sexual abuse or rejection for their gender identity or sexual orientation are less likely to experiment as well.
