No More Antibiotics and Pain Medication

I wanted to find out if anybody that used to take antibiotics (like cephalexin) and pain medication (like ibuprofen) during the year's sick season has stopped taking it because you replaced it by letting your body naturally heal and using marijuana as a pain aid?

I know it is not a 1 to 1 supplement, but they say the human body repairs itself if you give it time, so in theory you do not have to take antibiotics and pain medication--you just let you system do it's job.
