"In conclusion, our study of self-reported marijuana use by adolescents in states with a medical marijuana policy compared with a sample of geographically similar states without a policy does not demonstrate increases in marijuana use among high school students that may be attributed to the policies."
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.
"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.
"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)."
"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. Black and Hispanic individuals had the highest prevalence of PI, 20.6% and 14.8%, compared with 11.9% for white individuals and 11.6% for those classified as other.
"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%).
Estimated Daily Prevalence of Use of Various Drugs By US Youth In Grades 8, 10, and 12 Combined, According to the Monitoring the Future Survey -- Entries in Percentages
"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.
"Although availability of alcohol among 12th grade students is near its lowest level recorded since first measured in 1999, at 86% it is still very high.
"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, the most widely used of the illicit drugs, did not show any significant change in annual prevalence this year in any of the three grades, nor in the three grades combined. After rising for several years, the annual prevalence of marijuana has more or less leveled out since about 2010.
