The Peter F. McManus Charitable Trust will make grants of up to $50,000 for research into the causes of alcohol and other drug addiction.

A total of $150,000 to $200,000 in grants will be awarded this year to support basic, clinical, and social-environmental research. Only nonprofits may apply, and no more than 10 percent of the grant amount may be used for indirect costs.

Application deadline is Aug. 30. Applicants should submit a two- to three-page summary proposal and proposed budget along with a copy of their institution's 501(c)3 letter and a bio-sketch of the investigator.
