Hello everyone. =) disease and addiction. Well addiction can be mental and physical as well; the same stance as a disease. A disease is illness, sickness, toxicity or unfavorable environmental factors; any abnormal condition. In a sense, yes a addiction and disease go hand and hand because normally, if you have an addiction, it's spawned from some kind poison that is put into your body, cocaine, meth or any drug or anything that's not suppose to be in there. What makes an addiction a disease is the aftermath; that's the big part. Some people believe that drug addiction or alcohol addiction can be passed down from one generation to the next...kind of like a disease. So in a sense, the two are linked. May it be what your doing to your insides or what your doing to your family tree, addiction becomes a disease.
