Yesterday, shares surged as Canntab unveiled positive test results on its oral extended release formulation.
The firm said it would now begin manufacturing batches of these tablets for pharmacokinetic and clinical testing.
The testing was a collaboration with medical cannabis producer Emblem Corp (CVE:EMC, OTCQX: EMMBF) and showed that the pills released cannabinoids consistently over a 12-hour period.
Also yesterday, Canntab's plans to provide pot pills to patients and doctors in Canada was further advanced - as the company struck a definitive collaboration and profit sharing agreement with FSD Pharma.
As previously reported, the latter will help the firm to obtain a license to process and sell cannabis products and will provide it with up to 10,000 square feet at its facility, which lies one hour east of Toronto in Cobourg, Ontario.
