Of the 2 to 3 million homeless people in America, approximately 20 percent have a mental illness, said Charles Curie, SAMHSA administrator. Up to half of those have an alcohol or other drug use problem as well.

Thirty awards in 20 states are designed to expand and enhance treatment services for homeless people, building on 34 grants of a similar nature in 2004. The average grant size is $400,000 per year for five years.

Grantees ranged from tribal groups to healthcare centers, from Alaska to Florida. For a full list of awardees and their funded programs, go to SAMHSA online.
