                   File No. 333-230405

    Dear Mr. LoCascio:

           We have reviewed your response letter and have the following
comments. In some of our
    comments, we may ask you to provide us with information so we may better
understand your
    disclosure.

           Please respond to this letter by amending your registration
statement and providing the
    requested information. If you do not believe our comments apply to your
facts and
    circumstances or do not believe an amendment is appropriate, please tell us
why in your
    response.

           After reviewing any amendment to your registration statement and the
information you
    provide in response to these comments, we may have additional comments.

    Response Letter dated April 3, 2019

    Recent Developments

    Operating Results, page 10

        1. We note your proposed disclosure that you may include in a
subsequent amendment
           regarding your partial first quarter net sales, and it appears the
presentation of this
           preliminary result in isolation provides investors with an
incomplete picture of your
           financial results. Accordingly, we have the following comments:

           Please discuss the way(s) in which these results are consistent with
or different from
           your results of operations in prior periods. Please also expand your
disclosure to
           explain both quantitatively and qualitatively the factors that you
believe have
           contributed to the changes. The nature of any unusual or
nonrecurring items that have
           impacted or are expected to impact the preliminary results should
also be disclosed.
           We note your statement in your proposed disclosure that you..."may
identify items
           that require [you] to make adjustments to the financial information
set forth above
           and those changes could be material." If you choose to disclose
preliminary results,
           you should be able to assert that the actual results are not
expected to vary materially
           from that reflected in the preliminary results. Accordingly, please
remove this
           statement, as it implies that investors should not rely on the
information presented, or
           explain why the presentation of this information alongside a
disclaimer that the
           preliminary financial information could differ materially provides
meaningful
           disclosure to investors.

       Please also confirm your understanding that if, prior to the effective
date of your
       registration statement, more precise numbers become available as you
conduct your
       financial closing procedures for the quarter ended March 31, 2019, they
will be included
       in your registration statement.

Corporate Structure, Page 14

    2. We note that you show in the organizational charts here and on page 66
that investors in
       the offering will have a 22.6% economic interest in Greenlane Holdings,
Inc. We also
       note that you show that the founder and non-founder members will have no
economic
       interest in the registrant. We further note that in the third bullet
point on page 65, you
       state that purchasers in the offering will own 100% of the economic
interest in you.
       Please clarify for us what percentage of economic interest that
investors in the offering
       will own after the offering and update your disclosures as needed.

Dilution, page 71

    3. We note your dilution calculation and have the following comments.

           Please show us how you calculated your net tangible book value as of
December 31,
           2018 of $(12.6) million and net tangible book value per share of
$(0.34). It appears
           you have used 41,333,333 shares as outstanding in this calculation.
If so, please
           explain your basis for using this amount of shares as it appears to
be the amount of
           common units outstanding in the LLC and also to include the shares
purchased in this
           offering.
           Please also explain how this represents Class A common stock owned
by your
           founder and non-founding members, when it appears they will not hold
Class A stock
           but will be issued Class B and Class C common stock.

           For your net tangible book value per share after the offering of
$2.47, it appears you
           have also used 41,333,333 shares. Please explain to us why you
believe this is the
           appropriate amount of shares to use as this appears to be the common
units
           outstanding in the LLC and not the shares issued for the registrant.

    4. Please show us how you determined the amounts shown in the table on page
72. Please
       explain why you show new investors as purchasing 4,666,666 shares and
excluded the
       shares sold to new investors by selling shareholders. Please also
explain why the total
       number of shares is 41,333,333 shares as this appears to be the common
units outstanding
       for the LLC and not the total number of shares to be outstanding for the
registrant. Please
       finally show us how you determined the amount of total consideration
contributed by
       existing shareholders. We may have further comment.

    5. Please show us your calculations for the amounts in the final pro forma
Greenlane
       Holdings Inc. column for common units and additional paid in capital.
Please explain to
       us why there remains a balance in member's equity after giving effect to
the transactions
       and offering. Please also explain to us why you show a negative amount
in retained
       earnings for the amount of your non-controlling interest.
