Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Our unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2021. The condensed consolidated results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022, or any other future annual or interim period. Certain reclassifications have been made to prior year amounts or balances to conform to the presentation adopted in the current year.
Principles of Consolidation	Principles of Consolidation Our condensed consolidated financial statements include our accounts, the accounts of the Operating Company, and the accounts of the Operating Company's consolidated subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates Conformity with U.S. GAAP requires the use of estimates and judgments that affect the reported amounts in our condensed consolidated financial statements and accompanying notes. These estimates form the basis for judgments we make about the carrying values of our assets and liabilities, which are not readily apparent from other sources. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. U.S. GAAP requires us to make estimates and judgments in several areas. Such areas include, but are not limited to: the collectability of accounts receivable; the allowance for slow-moving or obsolete inventory; the realizability of deferred tax assets; the fair value of goodwill; the fair value of contingent consideration arrangements; the useful lives of intangible assets and property and equipment; the calculation of our VAT taxes receivable and VAT taxes, fines, and penalties payable; our loss contingencies, including our TRA liability; and the valuation and assumptions underlying equity-based compensation. These estimates are based on management's knowledge about current events and expectations about actions we may undertake in the future. Actual results could differ materially from those estimates. In March 2020, the World Health Organization declared the novel coronavirus ("COVID-19") a global pandemic. We expect uncertainties around our key accounting estimates to continue to evolve depending on the duration and degree of impact associated with the COVID-19 pandemic, including the possible resurgence of new strains. Our estimates may change as new events occur and additional information emerges, and such changes are recognized or disclosed in our condensed consolidated financial statements.
Segment Reporting	Segment ReportingWe manage our global business operations through our operating and reportable business segments. Due to our recent merger with KushCo, we reassessed and updated our operating segments. Therefore, beginning with the fourth quarter of 2021, we determined we had following two reportable operating business segments: (1) Industrial Goods, which largely comprises KushCo's legacy operations across the United States and Canada, and (2) Consumer Goods, which largely comprises Greenlane's legacy operations across the United States, Canada, and Europe. Our reportable segments have been identified based on how our chief operating decision maker ("CODM"), which is a committee comprised of our Chief Executive Officer ("CEO") and our Chief Financial Officer ("CFO"), manage our business, make resource allocation and operating decisions, and evaluate operating performance.
Revenue Recognition	Revenue Recognition Revenue under bill-and-hold arrangements was $0 and $0.2 million for the three months ended March 31, 2022 and 2021, respectively. Storage fees charged to customers for bill-and-hold arrangements are recognized as invoiced. Such fees were not significant for the three months ended March 31, 2022 and 2021. Our liability for returns, which is included within "Accrued expenses and other current liabilities" in our condensed consolidated balance sheets, was approximately $0.9 million and $1.0 million as of March 31, 2022 and December 31, 2021. The recoverable cost of merchandise estimated to be returned by customers, which is included within "Other current assets" in our condensed consolidated balance sheets, was approximately $0.2 million as of March 31, 2022 and December 31, 2021, respectively. For the three months ended March 31, 2022, one customer represented approximately 16% of our net sales. No single customer represented more than 10% of our net sales for the three months ended March 31, 2021. As of March 31, 2022, three customers represented approximately 17%, 10%, and 10% of accounts receivable, respectively. As of December 31, 2021, two customers represented approximately 13% and 11% of accounts receivable, respectively. Value Added Taxes During the third quarter of 2020, as part of a global tax strategy review, we determined that our European subsidiaries based in the Netherlands, which we acquired on September 30, 2019, had historically collected and remitted value added tax ("VAT") payments, which related to direct-to-consumer sales to other European Union ("EU") member states, directly to the Dutch tax authorities. In connection with our subsidiaries' payment of VAT to Dutch tax authorities rather than other EU member states, we may become subject to civil or criminal enforcement actions in certain EU jurisdictions, which could result in penalties. We performed an analysis of the VAT overpayments to the Dutch tax authorities, which we expected to be refunded to us, and VAT payable to other EU member states, including potential fines and penalties. Based on this analysis, we recorded VAT payable of approximately $1.0 million and $2.5 million relating to this matter within "Accrued expenses and other current liabilities" in our condensed consolidated balance sheet as of March 31, 2022 and December 31, 2021, respectively. Pursuant to the purchase and sale agreement by which we acquired our European subsidiaries, the sellers are required to indemnify us against certain specified matters and losses, including any and all liabilities, claims, penalties and costs incurred or sustained by us in connection with non-compliance with tax laws in relation to activities of the sellers. The indemnity (or indemnification receivable) is limited to an amount equal to the purchase price under the purchase and sale agreement. During the three months ended March 31, 2022, we recognized a gain of approximately $1.8 million within "general and administrative expenses" in our condensed consolidated statements of operations and comprehensive loss, which represented the partial reversal of a charge previously recognized based on the difference between the VAT payable and the VAT receivable and indemnification asset, as the indemnification asset became probable of recovery based on the reduction in our previously estimated VAT liability for penalties and interest based on our voluntary disclosure to, and ongoing settlement with, the relevant tax authorities in the EU member states. Management intends to pursue recovery of all additional losses from the sellers to the full extent of the indemnification provisions of the purchase and sale agreement, however, the collectability of such additional indemnification amounts may be subject to litigation and may be affected by the credit risk of indemnifying parties, and are therefore subject to significant uncertainties as to the amount and timing of recovery.As noted above, we have voluntarily disclosed VAT owed to several relevant tax authorities in the EU member states, and believe in doing so we will reduce our liability for penalties and interest. Nonetheless, we may incur expenses in future periods related to such matters, including litigation costs and other expenses to defend our position. The outcome of such matters is inherently unpredictable and subject to significant uncertainties.
Recently Issued Accounting Guidance Not Yet Adopted	Recently Issued Accounting Guidance Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses. The standard requires the use of an “expected loss” model on certain types of financial instruments. The standard also amends the impairment model for available-for-sale securities and requires estimated credit losses to be recorded as allowances rather than as reductions to the amortized cost of the securities.

Prior to this ASU, an acquirer generally recognizes contract assets acquired and contract liabilities assumed that arose from contracts with customers at fair value on the acquisition date. The ASU is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The ASU is to be applied prospectively to business combinations occurring on or after the effective date of the amendment (or if adopted early as of an interim period, as of the beginning of the fiscal year that includes the interim period of early application). We are still assessing this standard’s impact on our consolidated financial statements.

Our unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2021. The condensed consolidated results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022, or any other future annual or interim period. Certain reclassifications have been made to prior year amounts or balances to conform to the presentation adopted in the current year.

Principles of Consolidation

Our condensed consolidated financial statements include our accounts, the accounts of the Operating Company, and the accounts of the Operating Company's consolidated subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

Conformity with U.S. GAAP requires the use of estimates and judgments that affect the reported amounts in our condensed consolidated financial statements and accompanying notes.
