Two people have been charged over the spate of drug overdoses at the Gold Coast as toxicology results rule out the presence of "zombie" drug flakka.

On Sunday, a 24-year-old Bundall man was charged with supplying a dangerous drug.

On Wednesday, a man, 21, was charged for supply of a dangerous drug and possession of a dangerous drug after police attended a Surfers Paradise address.

Another man, 21, was also found at the address and issued with a notice to appear for possession of dangerous drugs and utensils, unrelated to the supply incidents.
