Flower is the smokable part of the cannabis plant that is most popular. Cannabis flower is rich in trichomes, which are the resin glands containing cannabinoids and terpenes, that produce effects ranging from relaxing to stimulating depending on the potency and ratios of each active compound. Effects can be felt immediately and last 2-4 hours typically with a peak reached within 30 minutes to an hour. – Description courtesy of iheartjane.com
