A pill container / dispenser that includes fingerprint recognition circuitry located in a cap associated therewith. The cap is locked on the container and no pill can be dispensed from the container without first moving the cap. When a person places their thumb on the cap of the pill dispenser, a computer chip reads the thumbprint. If the person is an authorized user, the cap will be unlocked from the container and released so a pill can be dispensed from the container. If the fingerprint is not recognized, the cap will remain locked in position so that no dispensing will occur. Furthermore, if the computer chip recognizes tampering, such as a continued effort to remove the cap by a non-authorized user, a chemical spray is sprayed from the cap into the container. The spray will dilute or destroy the potency of the pills remaining in the container.
