Quackery involves practicing medicine fraudulently or without proper qualifications. Quacks deceive the public by pretending to have medical skills and qualifications when they have no formal education or licenses. There are several types of quackery, including medical quackery using unproven treatments, nutritional quackery promoting untested supplements, and device quackery using unproven medical devices. Quackery can have harmful physical and psychological effects and potentially prolong illness or even cause death.
