If it's a good Mango Indica cut then that may just be your strain man. I have had some excellent couchy & narcotic Mango before and it was super stoney and potent just really good delicious herb and had a sweet sour exotic almost fruity mango juice aroma when you broke the buds up along with lots of sticky frost and a dank hashy aroma when burned. Really good strain if it's the right one and a nice knock you out night time buzz.
