In Reply.—Glaxo Wellcome's product Zyban
(bupropion hydrochloride) is marketed in 150-mg, sustained-release tablets
as an aid to smoking cessation treatment and is available only by prescription.
The product Zyban WSB, marketed by Scotts-Sierra Crop Protection Company,
is a fungicide for use on turf and ornamental plants. It is a powder packaged
in 3-lb bags generally sold by distributors to nursery and landscaping professionals.
Its labeling limits the use to such professionals and explicitly warns against
human ingestion. There have been no reports to Glaxo Wellcome of actual or
potential substitution of the fungicide for our smoking cessation product.
