Flavonoids are present in all parts of the cannabis plant, but they are more concentrated in the flowers, leaves, and stems. You can consume flavonoids by: Smoking or vaping cannabis: This is the most common way of consuming flavonoids, but it also exposes you to harmful combustion products and reduces the bioavailability of some flavonoids. Eating or drinking cannabis: This is a safer way of consuming flavonoids, but it also requires decarboxylation (heating) to activate some of them. You can make your own edibles or beverages with cannabis butter or oil, or buy ready-made products from dispensaries or online stores. Applying cannabis topically: This is a localized way of consuming flavonoids that can help with skin conditions, muscle soreness, and joint pain. You can use cannabis creams, balms, lotions, or oils that contain cannabis extracts or infusions.
