Jefferies' lawyer Chris Tennet said there was a disproportionate level of media attention on the case.
"I'm surprised at the level of activity for charges that are so minor," he said this afternoon. "He denies wrongdoing."
Crown prosecutor Jamie O'Sullivan declined to comment.
Jefferies was earlier charged with possessing drugs and a glass pipe for smoking methamphetamine.
An earlier charge of possessing LSD was today amended to one of possessing a class C drug.
Police alleged he had the illegal items in July.
In an earlier ruling by Justice David Collins, Jefferies was quoted as saying the items found belonged to other people.
Charges came after police raided Jefferies' home, business and BMW car in July.
Jefferies' name suppression lapsed at a hearing last month.
All psychoactive products became "unapproved" from May 1. A person found guilty of possessing an unapproved substance can be punished by a fine up to $500.
The other charges carry more serious penalties but a relatively small amount of drugs -- including less than half a gram of meth -- were allegedly found in July.
