The article addresses a spectrum of issues in a relatively impartial way. Racist aspects of marijuana enforcement are ignored. The cost statistics of police enforcement of marijuana laws sound incorrect, based upon other sources, but the article is a good read.
raising the drinking age did lead to lower alcohol consumption; the effect was modest but real. But then DiNardo hit on another analysis—comparing cannabis use in states that raised the drinking age early with those that did it later. And he found that indeed, there seemed to be a substitution effect. On average, among high school seniors, a 4.5 percent decrease in drinking produced a 2.4 percent increase in getting high.
excessive drinking causes nearly 80,000 deaths per year in the United States, compared to virtually none for pot. Trading alcohol consumption for cannabis use might be a pretty attractive deal.
BUT WHAT ABOUT THE GATEWAY EFFECT? This has been a perennial bogeyman of the drug warriors. Kids who use pot, the TV ads tell us, will graduate to ecstasy, then coke, then meth, and then—who knows? Maybe even talk radio.
