1.     We note your revised disclosure regarding the legality of your products.
Since it appears
       that your products do contain cannabinoid extracts that are themselves
Schedule I
       controlled substances, please revise to state that Marijuana and CBD
products are
       Schedule 1 controlled substances and clearly indicate the consequence of
this
       classification under federal law.
2.     We note your statement that you "may or may not be directly or
indirectly involved in
       any actual delta-9 tetrahydrocannabionol ("THC") research." Please
clearly disclose your
       current involvement in THC research.

3.     We note your revised disclosure in response to prior comment 4 and "that
FDA will
       continue to oversee "marketing claims" and the "process for drug
applications."" Please
       revise to disclose the effect of the United States Food and Drug
Administration's
       regulation on your business, including any requirement for FDA approval
of your
       products, the nature and duration of the FDA approval process, the
status of your products
       in this approval process, regulation of the manufacturing and labeling
of your products,
       post-market approval reporting and record keeping, and the regulation of
the advertising
       and promotion of your products. Also, please include an appropriate risk
factor that
       includes a discussion of sanctions for non-compliance with FDA
regulation.

4.     We acknowledge your revised disclosure in response to prior comment 5.
Please tell us
       whether you have or will also change the advertising, packaging and/or
labeling for your
       applicable products such that they no longer make any claims regarding
benefits of your
       products. For example, we note the article on your website, You Can Make
Your Own
       CBD Oil, which states "Hemp CBD has been proven in many studies that it
has many
       beneficial medical and health properties. This oil can help one find
"relief from arthritis,
       diabetes, alcoholism, schizophrenia, PTSD, MS, epilepsy, and chronic
pain.""

       amounts for the St. George secured convertible promissory note, as well
as the
       disclosures on page 20 of that filing quantifying the details of your

pages 23 and
       24 for the comparative interim periods for the first quarter of 2017 and
2016. Please
       revise both the interim discussion as well as the discussion of your
comparative annual
       periods for 2016 and 2015 to address the following:

            Given the significant increase in selling, general, and
administrative expenses
       between both the respective interim and annual periods, revise to
provide a tabular
       breakdown of the components of these expenses by purpose of the expense.
While your
       current disclosure indicates a portion of the increase is due to the
issuance of stock-based
       instruments, clearly quantify the amount of salary, marketing, and other
expenses by
       type.
            Clearly quantify and discuss the nature of the marketing and
consulting expenses,
       identifying the specific revenue streams to which the marketing related.
            Separately quantify the amount of research and development expenses
for each
       period presented, discussing any trends experienced. Tell us how you
considered whether
       such amounts warranted separate line item disclosure.

17.    We note your response to prior comment 9. It appears the trend, gross
profit margin,
       selling, general, and administrative expense, interest expense, and
other requested
       information are missing from your Form 10-Q for the quarter ended June
30, 2017.
        Confirm that, if material, all your future interim and annual
comparisons will remain
       compliant with Item 303(a) and (b) of Regulation S-K. Refer to the
Instructions to
       paragraph 303 of Regulation S-K that state, in part: "The discussion and
analysis shall
       focus specifically on material events and uncertainties known to
management that would
       cause reported financial information not to be necessarily indicative of
future operating
       results or of future financial condition. This would include
descriptions and amounts of
       (A) matters that would have an impact on future operations and have not
had an impact
       in the past, and (B) matters that have had an impact on reported
operations and are not
       expected to have an impact upon future operations. Where the
consolidated financial
       statements reveal material changes from year to year in one or more line
items, the
       causes for the changes shall be described to the extent necessary to an
understanding of
       the registrant's businesses as a whole; Registrants need not recite the
amounts of changes
       from year to year which are readily computable from the financial
statements. The
       discussion shall not merely repeat numerical data contained in the
consolidated financial
       statements."

Disclosure Controls and Procedures, page 24

18.    We note that you conclude that your disclosure controls and procedures
were not
       effective during the period ended June 30, 2017. Please tell us and
revise your
       disclosures in future filings to clearly discuss the material
weakness(es) you identified,
       when the material weaknesses were discovered, and the steps and status
of your plans to
       remediate the material weaknesses.
