i've smoked everytime i was sick for the past couple years. I heard that it'll prolong your sickness but i dont know if thats true since i healed just as quick as i always do. Only thing shitty about it is if u do it with a very sore throat, shit hurts like a bitch but the high is worth it. Plus it takes your mind off feeling shitty from your sickness and you just feel hiiiiiiigh.
