yeah smoking while your sick helps releive the shitty feeling for a while, but i always have to watch my hits, cuz if i take too big of one, bye bye to the throat, i cough my fucking ass off and my throat is fucked up the rest of the day, but that wont stop me from smoking, haha, and also yeah weed weakens your immune system, even if your sick or not, so your more likely to get sick the more you smoke weed, thats in the winter. but anyone hate being high and having to walk in the damn mid summer sun? fuck 95 degrees while high, it sucks ass.
