Cardinal Health, Inc.
7000 Cardinal Place
Dublin, OH  43017


Ladies and Gentlemen:

            I have acted as counsel to Cardinal Health, Inc., an Ohio
corporation (the "Company"), in connection with the Company's Registration
Statement on Form S-8 (the "Registration Statement") filed under the Securities
Act of 1933, as amended (the "Act"), relating to the issuance of up to 50,000
common shares, without par value (the "Common Shares"), of the Company pursuant
to the Syncor International Corporation Employees' Savings and Stock Ownership
Plan, as Amended and Restated (the "Plan").

            In connection with the foregoing, I have examined: (a) the Amended
and Restated Articles of Incorporation, as amended, and Restated Code of
Regulations, as amended, of the Company, (b) a copy of the Plan, and (c) such
records of the corporate proceedings of the Company and such other documents as
I deemed necessary to render this opinion. I have assumed that the copy of the
Plan I reviewed is the form approved by the Board of Directors of Syncor
International Corporation (or a committee thereof).

            Based on such examination, I am of the opinion that the Common
Shares available for issuance under the Plan, when issued, delivered and paid
for in accordance with the terms and conditions of the Plan, will be legally
issued, fully paid and nonassessable.

            For purposes of the opinions given herein, I do not purport to be a
member of the Bar of, or an expert on the laws of, any jurisdiction other than
the State of Ohio, and I express no opinion herein as to the laws of any
jurisdiction other than the laws of the State of Ohio.

            I hereby consent to the filing of this Opinion as Exhibit 5 to the
Registration Statement and the reference to me in Item 5 of Part II of the
Registration Statement. In giving such consent, I do not thereby admit that I am
in the category of person whose consent is required under Section 7 of the Act
or the rules and regulations of the Securities and Exchange Commission.


                                Very truly yours,

                                /s/ Amy H. Hunsaker

                                Amy H. Hunsaker, Esq.
                                Assistant General Counsel,
                                Securities and Corporate Governance
