SFP, your first study uses the following source for its statistics:
"A number of statistics were found that correlated drug addiction levels in various European countries. The following chart was created by information offered by the medical marijuana magazine."
Not my favorite source.. but this is interesting about alcoholism rates from Encyclopedia Britanica:
"Estimates of the prevalence of alcoholism vary depending on the definition used and upon the methods of estimation. In the United States 10 to 20 percent of men and 5 to 10 percent of women at some point in their lives will meet criteria for alcoholism, depending on the stringency of the criteria employed. These rates are similar to the rates for many countries in western Europe, and the rates are a little higher in eastern European countries. Rates in countries around the eastern Mediterranean and in Southeast Asia are much lower. Overall, rates in Africa are low, but they are very high in the new urban slums.
Variations in the definition of alcoholism, however, make it difficult to compare rates in different countries. In England and Wales, estimates of the prevalence of alcoholism have suggested rates that range from 1.1 to 11 percent, and in Switzerland the suggested rates range from 2.2 to 13 percent. The prevalence of alcoholism in France has been estimated at as high as 15 percent of the adult population, but more conservative estimates suggest 9 percent.
In Portugal, with one of the highest per capita alcohol-consumption rates in the world, did not even recognize alcoholism as a problem until the late 20th century. In the mid-20th century, the death of Soviet dictator Joseph Stalin resulted in a shift from official denial that any significant alcohol problem existed in the Soviet Union to an outcry that alcoholism involved 40 percent of adult males. In both circumstances, however, statistics were inadequate. In short, there is a strong subjective element in statistics of alcoholism. In addition, comparative data invariably fail to take account of changes in diagnostic policies and whether illicit, untaxed alcoholic beverages are included in estimates of national consumption."
**regarding your drunk driving stats:
On average someone is killed by a drunk driver every 45 minutes. In 2008, an estimated 11,773 people died in drunk driving related crashes??”a decline of 9.8 percent from the 13,041 drunk driving related fatalities of 2007.
These deaths constitute 31.6 percent of the 37,261 total traffic fatalities in 2008. (Source: NHTSA, 2009)
In 2007, an estimated 12,998 people were killed in alcohol-impaired driving crashes1 ??“ a decline of 3.7 percent from the 13,491 fatalities in 2006.
(Source: NHTSA-2007 Traffic Safety Annual Assessment)
Traffic fatalities in alcohol-impaired-driving crashes fell by 0.8 percent, from 13,582 in 2005 to 13,470 in 2006. The 13,470 alcohol-impaired-driving fatalities in 2006 were almost the same as compared to 13,451 alcohol-impaired-driving fatalities reported in 1996.
