Reduce the proportion of people who had marijuana use disorder in the past year — SU‑14 Data Methodology and Measurement

About the National Data

Data

Baseline: 1.6 percent of persons aged 12 years and over had a marijuana use disorder (defined as meeting DSM-IV criteria) in the past 12 months in 2018

Target: 1.3 percent

Numerator
Number of persons aged 12 years and over with marijuana use disorder (defined as meeting DSM-IV criteria) in the past 12 months.
Denominator
Number of persons aged 12 years and over.
Target-setting method
Projection
Target-setting method details
Linear trend fitted using weighted least squares and a projection at the 50 percent prediction interval.

Target-setting method justification
Trend data were evaluated for this objective. Using historical data points, a trend line was fitted using weighted least squares, and the trend was projected into the next decade. This method was used because three or more comparable data points were available, the projected value was within the range of possible values, and a projection at the 50 percent prediction interval was selected because no additional information could be used to assess the trend line, so the target was based on the projection.

Methodology notes

NSDUH respondents who used marijuana on 6 or more days in the past 12 months were categorized as having a marijuana use disorder if they met the DSM-IV criteria for either dependence or abuse for marijuana. Illicit drug use disorder is defined as meeting DSM-IV criteria for either dependence or abuse for one or more of the following illicit drugs: marijuana, cocaine, heroin, hallucinogens, inhalants, methamphetamine, or prescription psychotherapeutic drugs that were misused (i.e., pain relievers, tranquilizers, stimulants, and sedatives).


1. Because Healthy People 2030 objectives have a desired direction (e.g., increase or decrease), the confidence level of a one-sided prediction interval can be used as an indication of how likely a target will be to achieve based on the historical data and fitted trend.
