Before you start cooking with cannabis, it's important to understand a few key concepts. First, not all cannabis is created equal. Different strains of cannabis have different ratios of cannabinoids, the active compounds in the plant that produce the desired effects. THC (tetrahydrocannabinol) is the psychoactive compound that is responsible for the "high" associated with cannabis, while CBD (cannabidiol) is a non-psychoactive compound that is believed to have a range of potential health benefits.
