Nature of Operations [Policy Text Block]	Nature of Operations General Cannabis Corp, a Colorado Corporation (the “Company,” “we,” “us,” “our,” or “GCC”) (formerly, Advanced Cannabis Solutions, Inc.), was incorporated on June 3, 2013, and provides services and products to the regulated cannabis industry. On June 6, 2018 we began trading on the OTCQX® Best Market after upgrading from the OTCQB® Venture Market. Our operations are segregated into the following four segments: Security and Cash Transportation Services (“Security Segment”) We provide advanced security, including on-site professionals and cash transport, to licensed cannabis cultivators, cannabis processing facilities and retail shops, under the business name Iron Protection Group (“IPG”) in California and Colorado, and security services to non-cannabis customers in Colorado, such as hotels, apartment buildings and retail, under the business name Mile High Protection Services (“MHPS”), which we acquired in August 2017. Operations Consulting and Products (“Operations Segment”) Through Next Big Crop (“NBC”), we deliver comprehensive consulting services to the cannabis industry that include obtaining licenses, compliance, cultivation, retail operations, logistical support, facility design and construction, and expansion of existing operations. During the first quarter of 2019, 76% of NBC’s revenue was with one customer. NBC oversees our wholesale equipment and supply business, operated under the name “GC Supply,” which provides turnkey sourcing and stocking services to cultivation, retail and infused products manufacturing facilities. Our products include building materials, equipment, consumables and compliance packaging. There are generally multiple suppliers for the products we sell; however, there are a limited number of manufacturers of certain high-tech cultivation equipment. Consumer Goods and Marketing Consulting (“Consumer Goods Segment”) Our apparel business, Chiefton, has two primary revenue streams. Chiefton Supply strives to create innovative, unique t-shirts, hats, hoodies and accessories. Our apparel is sold through our on-line shop, cannabis retailers, non-cannabis retailers, and specialty t-shirt and gift shops. Chiefton Design provides design, branding and marketing strategy consulting services to the cannabis industry, which frequently includes sourcing and selling customer-specific apparel and accessories. Capital Investments and Real Estate (“Investments Segment”) As a publicly traded company, we have access to capital that may not be available to businesses operating in the cannabis industry. Accordingly, we may provide debt or equity capital through (a) loans or revolving lines of credit, (b) leasing real estate we own, or (c) investing in businesses using cash or shares of our common stock.
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation These unaudited condensed consolidated financial statements have been prepared following the requirements of the Securities and Exchange Commission (“SEC”), for interim reporting. As permitted under those rules, certain footnotes and other financial information that are normally required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) can be condensed or omitted. The condensed consolidated balance sheet for the year ended December 31, 2018 was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. The information included in this quarterly report on Form 10-Q should be read in conjunction with the consolidated financial statements and notes thereto of the Company for the year ended December 31, 2018 which were included in the annual report on Form 10-K filed by the Company on March 8, 2019. In the opinion of management, these condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and notes thereto of the Company and include all adjustments, consisting only of normal recurring adjustments, considered necessary for the fair presentation of the Company’s financial position and operating results. The results for the three months ended March 31, 2019 are not necessarily indicative of the operating results for the year ending December 31, 2019, or any other interim or future periods.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The accompanying condensed consolidated financial statements include the results of GCC and its five wholly-owned subsidiary companies: (a) 6565 E. Evans Owner LLC, a Colorado limited liability company formed in 2014; (b) General Cannabis Capital Corporation, a Colorado corporation formed in 2015; (c) GC Security LLC (“GCS”), a Colorado limited liability company formed in 2015; (d) GC Corp., a Colorado corporation, originally formed in 2013 named ACS Corp; and (e) GC-NY Health LLC, a Delaware limited liability company formed in 2019. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of our condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Although these estimates are based on our knowledge of current events and actions we may undertake in the future, actual results may ultimately differ from these estimates and assumptions. Furthermore, when testing assets for impairment in future periods, if management uses different assumptions or if different conditions occur, impairment charges may result.
Going Concern	Going Concern The condensed consolidated financial statements have been prepared on a going concern basis, which assumes we will be able to realize our assets and discharge our liabilities in the normal course of business for at least the twelve months from the date these condensed consolidated financial statements are issued. Our cash of approximately $5.6 million is not sufficient to absorb our operating losses and retire our debt of $6.8 million. The warrants associated with this debt, if exercised, would provide sufficient funds to retire the debt; however, there is no guarantee that these warrants will be exercised. Our ability to continue as a going concern is dependent upon our generating profitable operations in the future and / or obtaining the necessary financing to meet our obligations and repay our liabilities arising from normal business operations when they come due. Management believes that (a) we will be successful obtaining additional capital and (b) actions presently being taken to further implement our business plan and generate additional revenues provide opportunity for the Company to continue as a going concern. While we believe in the viability of our strategy to generate additional revenues and our ability to raise additional funds, there can be no assurances to that effect. Accordingly, there is substantial doubt about our ability to continue as a going concern. The accompanying condensed consolidated financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.
Related Parties [Policy Text Block]	Related Parties Related parties are any entities or individuals that, through employment, ownership or other means, possess the ability to direct or cause the direction of the management and policies of the Company. We disclose related party transactions that are outside of normal compensatory agreements, such as salaries or board of director fees. We consider the following individuals / companies to be related parties: · Michael Feinsod – Chairman of our Board of Directors (“Board”). · Infinity Capital West, LLC (“Infinity Capital”) – An investment management company that was founded and is controlled by Michael Feinsod. · DB Arizona – A company that borrowed $825,000 from GC Finance Arizona. Prior to our purchase in June 2017, we did not possess the ability to influence DB Arizona and DB Arizona did not have the ability to influence us. We include DB Arizona as a related party due to our relationship with Michael Feinsod and Infinity Capital, and their relationship with DB Arizona.
Notes Receivable Policy	Notes Receivable We classify our notes receivable as held for investment, because we have the intent and ability to hold our notes receivable to maturity or settlement. Direct loan origination costs we incur are netted with loan origination fees we receive and the net amount, loan origination fees or costs, is included in notes receivable on the condensed consolidated balance sheets. The loan origination fees or costs are amortized over the term of the underlying note receivable and included in interest income in the condensed consolidated statements of operations. We record an allowance for credit losses, as needed, using the current expected credit losses impairment model (“CECL Model”). The CECL Model requires us to consider relevant information about past events, current conditions, and reasonable and supportable forecasts of factors that affect the expected collectability of notes receivable. There is no probability of loss threshold that must be met prior to recording an allowance for credit losses under the CECL Model. We may assess notes receivable for impairment either on an aggregated basis, if they have sufficiently similar characteristics, or on an individual basis. Increases or decreases to the allowance for credit losses, if any, are included in net income in the condensed consolidated statements of operations.
RightOfUseAssetAndLeaseLiability	Right-of-use Asset / Lease Liability We adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-02 “Leases (Topic 842)” during the first quarter of 2019. We first evaluate our leases to determine whether they are classified as a finance lease or as an operating lease. A lease is a finance lease if any of the following criteria are met: (a) ownership transfers, (b) the lease includes an option to purchase the underlying asset, (c) the lease term is for the major part of the remaining economic life of the underlying asset, (d) the present value of the lease payments equals or exceeds the fair value of the underlying asset, or (e) the underlying asset is of a specialized nature that is expected to have no alternative use to the lessor at the end of the lease term. All of our leases are classified as operating leases. We then determine whether the short-term exemption applies; that is, is the lease term 12 months or less and does not include a purchase option whose exercise is reasonably certain. If the short-term exemption applies then lease payments are recognized as expense and no asset or liability is recorded. If the short-term exemption does not apply, then we record an operating lease right-of-use asset and a corresponding operating lease liability equal to the present value of the lease payments. All of our leases prior to 2019 met the short-term exemption, so modification to prior period results is not required. The two year commercial real estate lease we entered into in February 2019 did not meet the short-term exemption and, accordingly, we recorded the present value of the lease payments as a right-of-use asset and a lease liability in the condensed consolidated balance sheet. We recognize expense on a straight-line basis over the life of the lease.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards FASB ASU 2018-07 “Compensation – Stock Compensation (Topic 718)” - In June 2018, the FASB issued ASU 2018-07. This update is intended to reduce cost and complexity and to improve financial reporting for share-based payments issued to non-employees (for example, service providers, external legal counsel, suppliers, etc.). The ASU expands the scope of Topic 718, Compensation—Stock Compensation, which currently only includes share-based payments issued to employees, to also include share-based payments issued to non-employees for goods and services. Consequently, the accounting for share-based payments to non-employees and employees will be substantially aligned. This standard will be effective for financial statements issued by public companies for the annual and interim periods beginning after December 15, 2018. Early adoption of the standard is permitted. This ASU did not have a significant impact on our condensed consolidated financial statements and related disclosures. FASB ASU 2017-04 “Simplifying the Test for Goodwill Impairment (Topic 350)” – In January 2017, the FASB issued 2017-04. The guidance removes “Step Two” of the goodwill impairment test, which required a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The ASU is effective for annual reporting periods beginning after December 15, 2019, and for interim periods within those years, with early adoption permitted. We do not currently expect this ASU to have a significant impact on our condensed consolidated financial statements and related disclosures. FASB ASU 2016-02 “Leases (Topic 842)” – In February 2016, the FASB issued ASU 2016-02, which requires lessees to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting, but without explicit bright lines. Lessor accounting is similar to the current model, but has been updated to align with certain changes to the lessee model and the new revenue recognition standard. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.
