As any cannabis user or anyone who has seen a stoner movie will tell you, weed gives you the munchies. This is of course due to THC woking on areas of the brain to drive appetite and increase the pleasure experienced from food.
Cannabis strains high in the terpenes humulene and limonene can decrease appetite and higher than typical levels of CBD and CBG help tame the munchies. Strains containing the rare appetite surpassing THCV cannabinoid will be even more likely to curb trips to the fridge and even help with weight loss.
