On January 14, 2008 he signed a 1-year contract with the Milwaukee Brewers.

On March 13, 2008, Cameron applied for a therapeutic exemption to use stimulants during the 2008 season because of his outfield collision with former teammate Carlos Beltrán.
He claimed to be struggling with after-effects of the collision that ended his 2005 season.
 If he had applied for the exemption in 2007, he could have avoided the 25-game suspension he had to serve to begin this season for testing positive for a banned stimulant for the second time.
He also told USA Today that he will see a neurologist to determine if he is suffering from post-concussion syndrome.
 If the exemption is granted, Cameron would be permitted to use some amphetamines that are currently banned by the Major League Baseball drug policy.

In November 2008, his club option was picked up by the Brewers for the 2009 season.

On May 24, 2009, Cameron hit his 250th career home run against the Minnesota Twins, becoming the 20th player in the league to hit 250 home runs and steal 250 bases.
