The state constitutional amendment that legalized the drug's recreational use permits possession of up to 1 ounce of tetrahydrocannabinol (THC), the active ingredient that produces a euphoric high. Proponents of Amendment 64 said legalizing recreational sales and use of marijuana would stifle the black market in Colorado. That is not the case; crime statistics indicate we have more to learn about the long-term effects of legal pot on public safety and other concerns. Data indicate there is new black market trafficking across the country as a result of legalized pot sales in Colorado. Other safety concerns surrounding concentrates and their manufacture are consequences of legalization that were never anticipated. Many people think only in terms of the raw plant material that is dried and smoked and called marijuana. They envision an ounce of dried marijuana plant in a small bag or container - a form that yields about 40 standard cigarettes. They do not consider THC in concentrated and highly potent forms known as hash oil and wax, typically sold at potency levels between 80 percent and 90 percent THC. At that concentration, these products are a far cry from the weed smoked at Woodstock that was around 2 percent THC. THC concentrates are sprayed on and infused into foods and drinks called edibles. They are also loaded into electronic cigarettes, where the concentrate heats and is vaporized by the user for a faster, more intense high. Users talk about "waxing," "dabbing" and "vaping." One ounce of concentrated THC is the chemical equivalent of more than 2,800 average-size servings of edibles such as brownies or candy (the state has determined that an edibles serving size is 10 mg). Researchers say vaping one hit of THC is the equivalent of 1/20th of a gram. That means 1 ounce of hash oil is the rough equivalent of 560 standard hits. [sidebar] About the series The reporting team: editorial board members Pula Davis and Wayne Laugesen and local reporter Christine Tatum. After the first year of recreational pot sales, The Gazette takes a comprehensive look at the unintended consequences of legalizing sales and use of recreational marijuana. Day 1: Colorado has a fragile scheme for regulating legal marijuana and implementing a state drug prevention strategy. Day 2: One of the suppositions about legalizing pot was that underground sales would be curtailed, but officials say there is evidence of a thriving black market. Day 3: One teen's struggle to overcome his marijuana addiction shows how devastating the drug can be for younger, more vulnerable users. And employers face new workplace issues. Day 4: Amid the hoopla about recreational marijuana sales, the medical marijuana industry is flourishing and has its own set of complicated concerns. - --- MAP posted-by: Jay Bergstrom
