A method of isomerizing &#x394;9-tetrahydrocannabinol ('&#x394;9-THC') to &#x394;10-tetrahydrocannabinol ('&#x394;10-THC'). The method includes the steps of: extracting &#x394;9-THC from cannabis biomass, which optionally contains one or more of the components found in fire retardant such as PHOS-CHEK&#xae;; dewaxing of crude extracts by winterization; pH-adjusting extracts by washing the extracts in heptane solution with aqueous solutions of: citric acid, sodium bicarbonate, and brine; isomerizing &#x394;9-THC to &#x394;10-THC by exposure to suitable conditions and in the presence of a catalyst based on the components of fire retardant; vacuum distillation of &#x394;10-THC at a predetermined temperature range and vacuum level; collecting the distillate and redistilling it up to three times to acquire distillate containing less than 60% &#x394;10-THC; and purification of the MO-THC to a purity of 99% or greater by crystallization from n-pentane solution.
