"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%).
"Of the 36,667 drug overdose deaths with at least one mention of a specific drug, 52% mentioned only one specific drug (18,931 deaths), 26% mentioned two (9,351 deaths), 12% mentioned three (4,521 deaths), 6% mentioned four (2,041 deaths), and 5% mentioned five or more (1,823 deaths). Among drug overdose deaths with at least one mention of a specific drug, the average number of specific drugs mentioned was 1.9.
"Amphetamines are CNS stimulants and are used both medicinally and as drugs of abuse. Amphetamines are generally taken recreationally and to enhance performance (e.g., truck drivers staying awake). Ecstasy falls within this category, and as a methylated amphetamine derivative it also has hallucinogenic properties. Amphetamines have been associated with crash occurrence and could logically be associated with driving impairment both in the stimulation and withdrawal stages; in the latter case especially as the drug interacts with fatigue."
" In 2017, 46% of 8th graders and 63% of 10th graders thought that cigarettes would be fairly easy or very easy for them to get if they wanted some. In 2017 for the first time we asked about availability of cigarettes among 12th graders; 78% reported they would be fairly easy or very easy to get. A growing interest among state and local governments to increase the minimum age to 21 for the purchase of tobacco products suggests that availability may decrease for this age group in the coming years.
Estimated Lifetime Prevalence of Substance Use in the US by Those Aged 12 and Older (Numbers in Thousands)
"In 2018, 205,000 people aged 12 or older initiated methamphetamine use in the past year (Figures 26 and 30), which averages to about 560 people per day who initiated methamphetamine use (Table A.3A). The number of past year initiates in 2018 for methamphetamine use was similar to the numbers in 2015 to 2017. In 2018, an estimated 31,000 adolescents aged 12 to 17 used methamphetamine for the first time in the past year (Figure 30). The number of adolescents in 2018 who were methamphetamine initiates was similar to the numbers in 2015 to 2017.
US Military Use of Amphetamines: "During Vietnam both the Air Force and Navy made amphetamines available to aviators. Intermittently since Vietnam up through Desert Storm the Air Force has used both amphetamines and sedatives in selected aircraft for specific missions."
"In 2018, approximately 1.9 million people aged 12 or older used methamphetamine in the past year (Figure 10). This number of past year methamphetamine users corresponds to 0.7 percent of the population (Figure 15). The percentage of people aged 12 or older in 2018 who used methamphetamine in the past year was similar to the percentages in 2015 and 2017, but it was slightly higher than the percentage in 2016 (0.5 percent)."
