>In 1998, a grant from the National Institute of Justice to the University of Maryland resulted in a report to the NIJ, which among other statements, concluded that "D.A.R.E. does not work to reduce substance use." [...] The evidence suggested that, by exposing young impressionable children to drugs, the program was, in fact, encouraging and nurturing drug use.
>A ten-year study was completed by Donald R. Lynam and colleagues in 2006 involving one thousand D.A.R.E. graduates in an attempt to measure the effects of the program. After the ten-year period, no measurable effects were noted.
>In 2001, the Surgeon General of the United States, David Satcher, placed the D.A.R.E. program in the category of "Ineffective Primary Prevention Programs".
>In March 2007, the D.A.R.E. program was placed on a list of treatments that have the potential to cause harm in clients in the APS journal, Perspectives on Psychological Science.
It was, at best, ineffective. At worst it was harmful.
Pointless is quite wrong though. Drugs can be dangerous and because of it should require a lot of thought, education about, and respect if you partake on it but they are definitely not pointless.
If used in ways that doesn't affect someone negatively (and here is where the danger, education, and respect part comes in) it can provide life experiences that you could never, ever have by being sober.
Doesn't mean that a sober experience is subpar, it's just different, and it's ok if you want to live that way but it's not the only and "right" way to live a life.
There isn't much to be educated about. Scientific research about the long-term effects of any of these is inconclusive, even on alcohol and tobacco which is everywhere. All they know is smoking increases the risk of lung cancer.
The related "legalizing weed will make people use it less" was a common argument before it was legal. We were actually taught that in college. Did not seem like a good-faith argument.
