Statistics and other data regarding drug use and other risk-taking behavior among young people, as well as drug policies related to young people including prevention, education, social development, healthcare, mental health, and criminal justice.

Impact of Medical Marijuana Laws on Adolescent Marijuana Use

"Concerns about laws and policy measures that may inadvertently affect youth drug use merit careful consideration. Our study does not show evidence of a clear relationship between legalization of marijuana for medical purposes and youth drug use for any age group, which may provide some reassurance to policymakers who wish to balance compassion for individuals who have been unable to find relief from conventional medical therapies with the safety and well-being of youth.

Opioids Do Not Have Potential To Cause Malformations To An Embryo Or Fetus

"It is important to note that, contrary to alcohol, benzodiazepines and nicotine, opioids do not have teratogenic potential (3). Thus, special attention needs to be paid to dependence and abuse of legal substances and prescription drugs that can have severe consequences for the foetus and newborn, such as foetal developmental disorders or sudden infant death syndrome (Fetal Alcohol Spectrum Disorders Center for Excellence, 2013; McDonnell-Naughton et al., 2012)."

Estimated Population of Young Adults in the US With a Parent Who Has Ever Spent Time in Jail or Prison

Estimated Population of Young Adults in the US With a Parent Who Has Ever Spent Time in Jail or Prison: "The prevalence of any PI [Parental Incarceration] was 12.5% with the 95% confidence interval (CI) of 11.3% to 13.8%. The distribution of incarceration status by category was: neither parent (87.5%, 95% CI: 86.2%–88.7%), father only (9.9%, 95% CI: 8.9%–10.9%), mother only (1.7%, 95% CI: 1.4%–2.0%), and both parents (0.9%, 95% CI: 0.7%–1.2%). A significant association was found between race and PI.

Many Youth Discontinue Use of Alcohol, Tobacco, and Other Drugs by the Time They Leave High School

"Among 12th graders, the highest noncontinuation rate is observed for inhalants (69%), followed by MDMA (ecstasy, Molly) and crystal methamphetamine (ice) (both at 47%). Many inhalants are used primarily at a younger age, and use is often not continued into 12th grade. The rank ordering for noncontinuation of other drugs is as follows: methamphetamine, heroin, crack, narcotics other than heroin, tranquilizers, amphetamines, steroids, sedatives (barbiturates), cocaine, cocaine other than crack, hallucinogens, and LSD (all between 34% and 44%).

Availability of Cigarettes Among 8th and 10th Graders According To The Monitoring The Future Study

"The perceived availability of cigarettes continued a long-term decline in 8th and 10th grade to historic low levels, with a significant decline in 10th grade. (Availability of cigarettes in 12th grade was first asked this year, so trend data are not yet available). After holding fairly steady at very high levels for some years, perceived availability reported by 8th and 10th graders began to decline modestly after 1996, very likely as a result of increased enforcement of laws prohibiting sale to minors under the Synar Amendment and FDA regulations.

Young People in the US Report Declining Availability of Marijuana

"Marijuana has been the most consistently available illicit drug and has shown only small variations over the years (see Figure 9-5a). What is most noteworthy is how little change has occurred in the proportion of 12th graders who say that marijuana is fairly or very easy to get. By this measure, marijuana has been readily available to the great majority of American 12th graders (from 80% to 90%) since 1975.

Marijuana Use Prevalence and Trends Among Youth in the US

"• Marijuana is by far the most widely used illicit drug. Nearly half of all 12th graders (45%), nearly one third of 10th graders (31%), and over one in seven 8th graders (14%) reported some marijuana use in their lifetime. Among 12th graders, 37% reported some use in the past year, and 23% reported some use in the past month. Among 10th graders, the corresponding percentages were 26% and 16%, respectively, and among 8th grade students, 10% and 5.5%.
