Re: Growblox Sciences, Inc.
       Registration Statement on Form S-3
       Filed July 25, 2014
       File No. 333-197646

To Whom It May Concern:

Growblox Sciences, Inc. (the “Company”) desires to withdraw the registration statement marked as Form S-3 which was filed on July 25, 2014.  The Form S-3 designation was in error and should have been marked as a Form S-1 filing.  Accordingly, the registration statement on Form S-1 was correctly filed on September 26, 2014, and we now desire that the incorrect filing on July 25, 2014, be withdrawn.

Very truly yours,

/s/ Gary R. Henrie
