Pot, marijuana, cannabis or weed, it's all slight variations on a plant. Yet walking into a newly legal recreational pot shop can still be intimidating given the dizzying array of choices. Some shops have a discerning collection of bud. Nine or 10 carefully chosen strains behind the counter in hospital-like jars. Some have triple that amount. Add in the vaporizers, pipes and edibles, from suckers to brownies, puppy chow (a snack for humans, not pets) to gummy bears, chocolates to tinctures, and the selection alone can be somewhat overwhelming. Marijuana is most often classified via strains. Pineapple Express was a James Franco movie, but it was a strain before that. Maui Waui is a Kid Cudi hit, but it's also a popular strain. The biggest strains in Denver right now, according to industry site leafly.com are Blue Dream, Golden Goat, Flo and Sour Diesel. Most types of cannabis are broken down as indica or sativa. (Maui Waui is a sativa, Purple Kush is an indica.) Think of sativas as high-energy, awake, daytime strains and indica as late-night, couch-lock, sleepy strains. - The Denver Post - Cheri Hackett pitured left
