I smoked weed for the first time.. what happened?

that's all normal, it depends on the person it's true for a lot of people you have to smoke once or even a few time to feel its actual effects i smoked it like 5 times before it worked. also make sure you are smoking it properly like actually inhaling it into your lungs. if it burns the back of your throat a lot that means it is just hitting the back and coming back out which wouldn't get you high.
