When legal pot sales start in Washington State, heavily taxed and regulated new businesses will try to muscle into a market cornered by illegal drug dealers and semi-legal shops dispensing marijuana as a medicine. Consultants advising state regulators said it's highly uncertain how much of the market will gravitate to the state's new recreational pot system, reports the Tacoma News-Tribune. BOTEC Analysis Corporation said that the, “Medical market could be hobbled by legislative intervention, but another and perhaps even greater concern is competition from the black market.” The state Office of Financial Management assumes Washington's demand for marijuana is about 85 million grams a year. Washingtonians actually consume nearly twice that amount, 165 million grams a year, consultants said. They said it seems unrealistic that the market under the pot legislation measure “ill be able to replace the illegal market any time soon.”
