The 37-year-old study, Monitoring the Future (MTF), received NIH funding for another 5 years, making it one of the largest and longest running investigator-initiated research studies supported by NIH. Lloyd Johnston says he and colleagues Jerald Bachman, Patrick O’Malley, John Schulenberg, and Megan Patrick hope that MTF will be a “national institution that continues beyond the careers of the current investigators,” some of whom were founding investigators in 1975.
