New study shows dramatic shifts in substance abuse treatment admissions among the states between 1998 and 2008

Nationwide percentage of treatment admissions primarily linked to alcohol has declined, while the percentage primarily linked to illicit drugs has increased

Although the overall rate of admissions to substance abuse treatment in the U.S. remained stable between 1998 and 2008, at about 770 admissions for every 100,000 persons in the population, a new study shows striking changes and variations in admission rates by region. For example, the rate of admissions for alcohol as the primary drug has declined by 15 percent nationally. However admission rates for alcohol in West North Central states (Ark., Iowa, Kan., Minn., Mo., N.D., Neb. and S.D.) remained the same.

At the same time that admissions for alcohol treatment were declining, admission rates per 100,000 population for illicit drug use were increasing. In fact, one consistent pattern in every region was the increase in the admission rate for marijuana use which rose 30 percent nationally. From 1998 through 2008, marijuana treatment admission rates were highest in the West North Central and Middle Atlantic states (N.J., N.Y. and Pa.).

As indicated in an earlier SAMHSA report, Substance Abuse Treatment Admissions Involving Abuse of Pain Relievers: 1998 and 2008: http://oas.samhsa.gov/2k10/230/230PainRelvr2k10.cfm, the treatment admission rate for opiates other than heroin (mainly narcotic pain relievers) rose 345 percent nationwide during these 11 years. The new study shows that increased admissions for pain reliever abuse occurred in every region of the nation and were highest in the New England (Conn., Mass., Maine, N.H., R.I. and Vt.) and the East South Central states (Ala., Ky., Miss. and Tenn.).

Nationwide, the admission rate for methamphetamine treatment was 53 percent higher in 2008 than in 1998, although the level has dropped significantly and consistently from its peak in 2005. Methamphetamine admission rates were highest during this period in the Pacific (Alaska, Calif., Hawaii, Ore. and Wash.), West North Central and Mountain states (Ariz., Colo., Idaho, Mont., Nev., N.M., Utah and Wyo.).
