why

my friend says every time he smokes his head pumps and hurts on the side of his head. anyone know why this happenes everytime he smokes

Is he smoking bad weed? That will give you a headache. Is the weed laced? I had a situation like that happen when I was younger, apparently I was smoking stuff laced with angel dust for like a week before I was told...that stuff will give you a headache....and I didn't enjoy it. SAY NO TO ANGEL DUST KIDS
