Some of the major sponsors of the event are pulling out after pressure from supporters of Measure 91 -- which seeks to legalize marijuana in the state.
Jefferson County District Attorney Steve Leriche is trying to raise the funds privately to make up for the loss.
"This conference and previous conferences have been sponsored by Best Care long before Meausre 91 ever existed. So to say it's associated with defeating the measure, that's a little bit of a stretch to me."
The Madras event scheduled for October was gonig to bring in a former White House Drug Advisor who opposes marijuana legalization.
Supporters of Measure 91 feel its wrong to use federal money from a grant to pay for a public appearance on this issue so close to the November election.
