Accounting Policies [Abstract]
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 6 months ended June 30, 2019, 76% of NBC’s revenue was with three customers. 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. Our CBD retail business, STOA Wellness, opened in July of 2019. STOA Wellness offers a curated collection of high quality CBD products for athletes and general wellness. Capital Investments and Real Estate (“Investments Segment”) As a publicly traded company, we believe that 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 and six months ended June 30, 2019 are not necessarily indicative of the operating results for the year ending December 31, 2019, or any other interim or future periods.
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 $800,000 is not sufficient to absorb our operating losses and repay our debt of $1.1 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 that we will be successful in such efforts. 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 loss 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)” on January 1, 2019. We first evaluated 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 determined 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 recorded 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 entered into prior to 2019 met the short-term exemption, so modification to prior period financial position was 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 rent expense on a straight-line basis over the life of the lease.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments GAAP requires disclosing the fair value of financial instruments to the extent practicable for financial instruments which are recognized or unrecognized in the consolidated balance sheet. The fair value of the financial instruments disclosed herein is not necessarily representative of the amount that could be realized or settled, nor does the fair value amount consider the tax consequences of realization or settlement. In assessing the fair value of financial instruments, the Company uses a variety of methods and assumptions, which are based on estimates of market conditions and risks existing at the time. For certain instruments, including accounts receivable and accounts payable, the Company estimated that the carrying amount approximated fair value because of the short maturities of these instruments. All debt is based on current rates at which the Company could borrow funds with similar remaining maturities and approximates fair value. GAAP establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use on unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs consist of items that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is described below: Level 1 – Quoted prices in active markets for identical assets or liabilities. There are no fair valued assets or liabilities classified under Level 1 as of June 30, 2019 and December 31, 2018. Level 2 – Observable prices that are based on inputs not quoted on active markets but corroborated by market data. There are no fair valued assets or liabilities classified under Level 2 as of June 30, 2019 and December 31, 2018. Level 3 – Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs (see Note 9). Level 3 liabilities are valued using unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the liabilities. For fair value measurements categorized within Level 3 of the fair value hierarchy, the Company’s accounting and finance department, which reports to the Chief Financial Officer, determines its valuation policies and procedures. The development and determination of the unobservable inputs for Level 3 fair value measurements and fair value calculations are the responsibility of the Company’s accounting and finance department and are approved by the Chief Financial Officer. Level 3 Valuation Techniques: Level 3 financial liabilities consist of the derivative liabilities for which there is no current market for these securities such that the determination of fair value requires significant judgment or estimation. Changes in fair value measurements categorized within Level 3 of the fair value hierarchy are analyzed each period based on changes in estimates or assumptions and recorded as appropriate. The Company deems financial instruments which do not have fixed settlement provisions to be derivative instruments. In accordance with U.S. GAAP the fair value of these warrants is classified as a liability on the Company’s consolidated balance sheets because, according to the terms of the warrants, a fundamental transaction could give rise to an obligation of the Company to pay cash to its warrant holders. Such instruments do not have fixed settlement provisions and have also been recorded as derivative liabilities. Corresponding changes in the fair value of the derivative liabilities are recognized in earnings on the Company’s consolidated statements of operations in each subsequent period. The Company’s derivative liabilities are carried at fair value and were classified as Level 3 in the fair value hierarchy due to the use of significant unobservable inputs. In order to calculate fair value, the Company uses a standard Black-Scholes model
Derivatives, Policy [Policy Text Block]	Equity Instruments Warrants with derivative features – When we raise capital by issuing warrants that do not have complex terms, they are recorded as additional paid in capital in our condensed consolidated balance sheet. When we issue warrants that have complex terms, such as a clause in which the warrant agreements contain a cash settlement provision whereby the holders could settle the warrants for cash upon a fundamental transaction that is considered outside of the control of management, such as a change of control, the warrants are considered to be a derivative that are recorded as a liability at fair value. The warrant derivative liability is adjusted to its fair value at the end of each reporting period, with the change being recorded as expense or gain. Equity issuance costs associated with a capital raise transaction are allocated between expense and additional paid-in capital based on the relative fair value of the instruments being issued. The expense is included in amortization of debt discount and equity issuance costs on the condensed consolidated statements of operations, and the equity allocation as a reduction of additional paid-in capital in our condensed consolidated balance sheet.
