OLYMPIA, Washington, May 16: Key officials helping to create Washington state’s potentially lucrative recreational pot market say its success may hinge on preventing consumers from choosing to get high on readily available medical cannabis because of low and sometimes nonexistent taxes on it. The officials say it may be necessary to raise taxes or impose more stringent rules on medical pot to avoid undercutting the new recreational market and the tax dollars it is expected to inject into state coffers. Many ‘patients,’ they say, are in reality heavy recreational users who fake or exploit their maladies. (agencies)
