I've heard that blazin lowers your immune system but i also heard in health that drinking soda lowers your immune system. But i don't wanna belive any so called "facts" in my health class because there is a poster on the wall the one that says "So you think weed isn't so bad? Well smoking one marijuana cigarete has the same amount of chemicals as if you smoked 4 cigarete's"

You could have gotten that cold from anywhere a door handle in school or some random kid that was coughing like a foot away from you or some shit you just didn't realize it at the time. If you pay attention when one person has a cold in a place like school seems like everyone does.
