You don't have to be a cannabis connoisseur to know how a certain type of flower might affect you. In fact, a simple smell test may provide a fairly accurate picture of what a strain's effects could feel like. When you're looking to buy a sativa, for instance, if the bud has a bright, uplifting, or floral aroma, chances are the high will also make you feel uplifted. But be careful — as much as sativas can provide a boost of energy, they my also cause more anxiety than their indica cousins. For that reason, if you're inexperienced with cannabis or prone to feeling anxious, opt for a high CBD blend (since CBD counteracts THC), or be sure to have CBD handy when trying out your new choice of cannabis.
