Data Interpretation Issues
SAMHSA generated state estimates based on a survey-weighted hierarchical Bayes estimation approach, and 95 percent confidence
intervals were generated by Markov Chain Monte Carlo techniques. Due to small sample sizes, NSDUH data is only available
at the state level for North Carolina.
Why Is This Important?
"Illicit drugs include marijuana/hashish, cocaine (including crack), heroin, hallucinogens, inhalants, or prescription-type
psychotherapeutics used for nonmedical purposes. Because addiction is a disease that often begins in childhood and adolescence,
it is particularly important to prevent and to reduce use among youth." - North Carolina Institute of Medicine. Healthy North
