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 April 28, 2015, our common stock was uplisted and on May 6, 2015, resumed quotation on the OTC Market’s OTCQB. 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”). We strategically acquired MHPS in order to expand our Colorado security business into the non-cannabis space, as we believe that market provides an opportunity for growth. In states that have recently legalized cannabis, whether medical, recreational or both, license applications require a security plan and, if approved, implementation of that security plan. Accordingly, we are assessing the opportunity to expand our security consulting business to assist companies with their application process and the subsequent implementation of security plans. Marketing Consulting and Apparel (“Marketing Segment”) Chiefton’s apparel business, Chiefton Supply, strives to create innovative, unique t-shirts, hats, hoodies and accessories. Our apparel is sold through our on-line shop, festivals and events, cannabis retailers, and specialty t-shirt and gift shops. We are pursuing relationships with national apparel retailers and distributors, as well as expanding our offerings nationwide within the cannabis industry. Chiefton Design provides design, branding and marketing strategy consulting services to the cannabis industry. We assist clients in developing a comprehensive marketing strategy, as well as designing and sourcing client-specific apparel and products. Chiefton Design also supports our other segments with marketing designs and apparel. 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. Our business plan for NBC correlates to future growth of the regulated cannabis market in the United States. 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 infrastructure, equipment, consumables and compliance packaging. Finance and Real Estate (“Finance Segment”) Real Estate Leasing On December 29, 2017, we sold for $625,000 in cash a cultivation property in a suburb of Pueblo, Colorado, consisting of approximately three acres of land, which currently includes a 5,000 square foot steel building and a parking lot. We previously leased this property to a licensed medical cannabis grower. Our real estate leasing business plan includes the potential future acquisition and leasing of cultivation space and related facilities to licensed marijuana growers and dispensary owners for their operations. These facilities would only be leased to tenants that possess the requisite state licenses to operate cultivation facilities. The leases with the tenants would include certain requirements that permit us to continually evaluate our tenants’ compliance with applicable laws and regulations. Shared Office Space, Networking and Event Services In October 2014, we purchased a former retail bank located at 6565 East Evans Avenue, Denver, Colorado 80224, which has been branded as “The Greenhouse.” The building is a 16,056 square foot facility, which we use as our corporate headquarters. The Greenhouse has approximately 10,000 square feet of existing office space and 5,000 square feet on its ground floor that is dedicated to a consumer banking design. We continue to assess the opportunity to lease shared workspace for entrepreneurs, professionals and others serving the cannabis industry. Clients would be able to lease office, meeting, lecture, educational and networking space, and individual workstations. We expect to continue the renovation of The Greenhouse in 2018. We plan to continue to acquire commercial real estate and lease office space to participants in the cannabis industry. These participants may include media, internet, packaging, lighting, cultivation supplies and financial services-related companies. In exchange for certain services that may be provided to these tenants, we expect to receive rental income in the form of cash. In certain cases, we may acquire equity interests or provide debt capital to these businesses. Industry Finance Our industry finance strategy includes evaluating opportunities to make direct term loans or to provide revolving lines of credit to businesses involved in the cultivation and sale of cannabis and related products. These loans would generally be secured to the maximum extent permitted by law. We believe there is a significant demand for this type of financing. We are assessing other finance services including customized finance, capital formation and banking, for participants in the cannabis industry.
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying (a) condensed consolidated balance sheet at December 31, 2017, has been derived from audited financial statements and (b) condensed consolidated unaudited financial statements as of June 30, 2018 and 2017, have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements, and should be read in conjunction with the audited consolidated financial statements and related footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2017 (the “2017 Annual Report”), filed with the Securities and Exchange Commission (the “SEC”) on March 12, 2018. It is management’s opinion, however, that all material adjustments (consisting of normal recurring adjustments), have been made which are necessary for a fair financial statements presentation. The condensed consolidated financial statements include all material adjustments (consisting of normal recurring accruals) necessary to make the condensed consolidated financial statements not misleading as required by Regulation S-X, Rule 10-01. Operating results for the three and six months ended June 30, 2018, are not necessarily indicative of the results of operations expected for the year ending December 31, 2018. The condensed consolidated financial statements include the results of GCC and its six wholly-owned subsidiary companies: (a) ACS Colorado Corp., a Colorado corporation formed in 2013; (b) Advanced Cannabis Solutions Corporation, a Colorado corporation formed in 2013; (c) 6565 E. Evans Avenue LLC, a Colorado limited liability company formed in 2014; (d) General Cannabis Capital Corporation, a Colorado corporation formed in 2015; (e) GC Security LLC (“GCS”), a Colorado limited liability company formed in 2015; and (f) GC Finance Arizona LLC (“GC Finance Arizona”), an Arizona limited liability company. Advanced Cannabis Solutions Corporation has one wholly-owned subsidiary company, ACS Corp., which was formed in Colorado on June 6, 2013. Intercompany accounts and transactions have been eliminated. During the year ended December 31, 2017, we adopted Financial Accounting Standards Board, or FASB, Accounting Standards Update, or FASB ASU 2017-11, which impacts accounting for financial instruments with down round features. This change in accounting principle was applied retrospectively and, accordingly, impacted all 2017 periods presented. See Note 14.
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 the foreseeable future. Our cash reserves of $10,173,382 are not sufficient to absorb our operating losses and retire our debt of $6,993,000. 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.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition During the first quarter of 2018, we adopted the following accounting principles related to revenue recognition: (a) FASB ASU 2016-12 “Revenue from Contracts with Customers (Topic 606);” (b) FASB ASU 2016-11 “Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815);” and (c) FASB ASU 2016-10 “Revenue from Contracts with Customers (Topic 606).” Due to the nature of our contracts with customers, adopting the new accounting principles did not have a significant impact on our prior period results of operations, cash flows or financial position. Our service and product revenues arise from contracts with customers. Service revenue includes (a) Security Segment, (b) Operations Segment consulting revenue, and (c) Marketing Segment revenues from design consulting, including customer-branded apparel designed and fulfilled by Chiefton. Product revenue includes (a) Operations Segment product sales and (b) Marketing Segment Chiefton-branded apparel. The majority of our revenue is derived from distinct performance obligations, such as time spent delivering a service or the delivery of a specific product. We may also enter into contracts with customers that identify a single, or few, distinct performance obligations, but that also have non-distinct, underlying performance obligations. These contracts are typically fulfilled within one to three months. Only an insignificant portion of our revenue would be assessed for allocation between distinct (contractual) performance obligations and non-distinct deliverables between reporting periods and, accordingly, we do not record a contract asset for completed, non-distinct performance obligations prior to invoicing the customer. We recognize revenue when the following criteria are met: The parties to the contract have approved the contract and are committed to perform their respective obligations – our customary practice is to obtain written evidence, typically in the form of a contract or purchase order. Each party’s rights regarding the goods or services have been identified – we have rights to payment when services are completed in accordance with the underlying contract, or for the sale of goods when custody is transferred to our customers either upon shipment to or receipt at our customers’ locations, with no right of return or further obligations. The payment terms for the goods or services have been identified – prices are typically fixed and no price protections or variables are offered. The contract has commercial substance – our practice is to only enter into contracts that will positively affect our future cash flows. Collectability is probable – we typically require a retainer for all or a portion of the goods or services to be delivered, as well as continually monitoring and evaluating customers’ ability to pay. Payment terms are typically zero to fifteen days within delivery of the good or service. Customer deposits are contract liabilities with customers that represent our obligation to either transfer goods or services in the future, or refund the amount received. Where possible, we obtain retainers to lessen our risk of non-payment by our customers. Customer deposits are recognized as revenue as we perform under the contract
Equity Method Investments [Policy Text Block]	Equity-method Investments We use the equity method for investments when we are able to exercise significant influence over, but do not control, the investee, and are not the primary beneficiary of the investee’s activities. We include our portion of an equity-method investee’s net income or loss within other expense on the condensed consolidated statements of operations. In the event that the cost basis in an investment exceeds the fair value of the underlying business, we record an impairment charge to reduce our carrying value to the estimated fair value.
New Accounting Pronouncements, Policy [Policy Text Block]	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.
Accounting Standards Update 2017-04 [Member]
Accounting Policies, by Policy (Policies) [Line Items]
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. The standard will be applied in a retrospective approach for each period presented. Management currently does not plan to early adopt this guidance and is evaluating the potential impact of this guidance on the consolidated financial statements as well as transition methods. 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 consolidated financial statements and related disclosures.
