It's works for me. As far as im concerned weed is the cure for the common cold. At the biggining of the year i had a cold and a chest infection, and couldnt be bothered with getting anti-biotics from the doctor so i just smoked up, and within a week, my cold had gone and so had my chest infection [And chest infections dont just go without meds]

And i got a chest infection right now, so what am i doing? Smoking up. It's nearly gone, only been 4 days.

I think it's because THC has anti0biotic properties [which is a proven fact]
