Equity [Abstract]
Common Stock	7. Common Stock Effective January 30, 2017, all holders of the $645,000 original principal amount of convertible debt converted their debt, which totaled $725,584, consisting of the outstanding principal amount and accrued and unpaid interest as of the date of conversion, into 6,868,578 shares of Common Stock (see Note 6). In March 2017, Dennis Di Ricco, who formerly served as the trustee of Acaccia, along with his family members and trusts) relinquished voting and investment power over all securities of the Company they owned, which constituted approximately 22% of the outstanding Common Stock of the Company. Mr. Di Ricco also surrendered his options to purchase up to 7,000,000 shares of common stock for forfeiture and cancellation (see Note 9), and sold (in a private transaction to which the Company was not a party) all 2,500,000 shares of Common Stock held as of record by his IRA. In connection with the foregoing, the Company and Mr. Di Ricco also terminated their consulting relationship. In March 2016, the Company entered into a consulting agreement with Redwood Group International Limited (“Redwood”). In exchange for its services, Redwood received $5,000 per month in retainer payments and was eligible to receive other fees and warrants, as set forth in the consulting agreement. The initial term of the consulting agreement was 12 months, ending on February 28, 2017, although the term would automatically extend for an additional 12 months unless terminated by either party. On September 29, 2016, the Company executed a letter agreement with Redwood, pursuant to which it issued to Redwood an additional 100,000 shares of Common Stock, subject to Redwood satisfying certain performance thresholds. If Redwood failed to meet such performance thresholds, the agreement provided the Company with an exclusive option to reacquire all or a portion of the shares of Common Stock at $0.00001 per share. On November 15, 2016, the Company and Redwood agreed to terminate the original consulting agreement and entered into a new consulting agreement that was set to expire upon thirty days’ written notice by either party following the successful completion of the Company’s IPO. The new consulting agreement was substantially similar to the prior agreement with respect to fees and warrants due to Redwood, and provided that the Company would pay Redwood a sum of $800,000 and issue Redwood a warrant to acquire 350,000 shares of Common Stock. In May 2017, the Company and Redwood mutually agreed to terminate this agreement. On June 8, 2017, the Company paid a fee of $800,000 to Redwood and issued Redwood a warrant to purchase 350,000 shares of Common Stock, in connection with which the Company cancelled the 100,000 shares of Common Stock it had previously issued pursuant to the September 2016 letter agreement. The warrant to purchase 350,000 shares of Common Stock was valued using the Black-Scholes method resulting in a fair market value of $1.24 million, which was charged to consulting expense for the year ended December 31, 2017. The assumptions used in the valuation included the term of 5 years, the exercise price of $5.00 per share, volatility of 92% and a risk-free interest rate of 1.75%. The fair value of the warrant was recorded as consulting expense during the year ended December 31, 2017. On June 9, 2017, the Company consummated the final closing of the IPO. The Company sold an aggregate of 2,852,275 shares of Common Stock, of which 342,273 shares were sold on behalf of certain stockholders of the Company who elected to participate in the IPO, for aggregate gross proceeds of $14,261,375. Net proceeds received after deducting commissions, expenses and fees of approximately $2.5 million and the $1,711,365 proceeds remitted to selling stockholders for the sale of their shares, amounted to approximately $10.0 million. As such, the Company issued and sold an aggregate of 2,510,002 shares of Common Stock in connection with the IPO, excluding the shares sold by the selling stockholders. In connection with the final closing of the IPO on June 9, 2017, the Company issued an additional 250,000 shares of Common Stock, valued at $1,250,000 under the terms of a consulting agreement. Under the terms of the underwriting agreement executed in connection with the IPO, the Company issued to Boustead Securities, LLC a warrant to purchase 199,659 shares of Common Stock. The warrant to purchase 199,659 shares of Common Stock was valued using the Black-Scholes option-pricing model resulting in a fair market value of $680,543. The assumptions used in the valuation included the term of 5 years, the exercise price of $6.00 per share, volatility of 92% and a risk-free interest rate of 1.75%. The fair value of the warrant was recorded as offering costs and netted against additional paid in capital during the year ended December 31, 2017. On January 9, 2018, the Company consummated the closing of a follow-on offering of units, each consisting of one share of common stock and a warrant to purchase 1.5 shares of common stock at an exercise price of $4.50. The Company sold an aggregate of 3,666,667 units for aggregate gross proceeds of approximately $11.0 million. Net proceeds received after deducting commissions, expenses and fees of approximately $1.2 million amounted to approximately $9.8 million. Under the terms of the underwriting agreement executed in connection with the follow-on offering, the Company issued to Boustead Securities, LLC and Roth Capital Partners, LLC warrants to purchase an aggregate of 256,667 shares of common stock. The warrants to purchase 256,667 shares of common stock were valued using the Black-Scholes option-pricing model, resulting in a fair market value of $598,737. The assumptions used in the valuation of the warrants issued to Boustead Securities, LLC and Roth Capital Partners, LLC included the term of five years, the exercise price of $3.75 per share, volatility of 92.20% and a risk-free interest rate of 2.13%. The fair value of these warrants was recorded as offering costs and netted against additional paid-in capital during the three months ended March 31, 2018. During May, June and August 2018, certain non-employees exercised options to purchase an aggregate of 994,695 shares of common stock, for which the Company received aggregate gross proceeds of $99,470 (see Note 9).
