"There's no truth in labelling now because there's no testing," Butt said. He is concerned that there is no way to ensure cannabis sold for medicinal use contains any of a substance shown to produce the medical benefits marijuana is promoted to address. Instead, the plant has been mainly produced to maximize its content of the substance that produces intoxication. Butt said he believes most of the "medical marijuana" that's sold is actually purchased for recreational use. "This unregulated marketing is such a free-for-all, it's a bit of a mess ... It's going to be a much more regulated environment, which is good." Butt said he is pleased the task force recommends legislation be written from a public health approach, seeking to minimize harm and use the revenue for education and research that will increase knowledge. "It's important not to just demonize it. That doesn't help, but rather to parse it out and say, 'This is what puts people at risk and this is what's potentially beneficial.' " Cannabis contains about 100 different chemical compounds called cannabinoids, which have various effects on the body when consumed. The most studied of cannabinoids are THC and CBD. The former affects the brain and causes the euphoric high that recreational users seek, along with other benefits and risks, while CBD does not cause intoxication and has been found to be protective of the brain by, for example, preventing medication-resistant seizures and counteracting the negative effects of THC, such as anxiety. Marijuana advocates say the compounds are most beneficial in combination. Butt said he supports the recommendation to place higher taxes on higher THC potency marijuana, which is likely to create a market demand for lower potency strains and encourage growers to produce them. He said adolescent marijuana use is particularly worrisome for him because of evidence that points to a connection between cannabis use and long-term psychiatric disorders. Human brains are not fully developed until the mid-20s, so early exposure to psychoactive drugs can affect that development, he said. - --- MAP posted-by: Matt
