It may not have been the bud at all. could have been what you ate. Or the combination of such goodness all at once made you sick. hard to say. I've never puked from smoking so sorry i can't relate.
The theory of it being your first time is valid we all react differently our first time. Try eating first and then smoking hold off the urge to eat for few hours and see how you react. also check the food to make sure it's not spoiled. good luck next time.
