Reliance on addictive substances is a negative coping mechanism.

Yes, drugs are indeed a negative coping mechanism. Psychologists believe that the need to abuse narcotic drugs is a result of an underlying problem that needs to be unearthed and expressed openly. People who are experiencing drug abuse often are mentally and emotionally unstable and should seek professional help. They either end up hurting themselves or other people, sometimes without the knowledge of it.  

Those recovering from the abuse attend group sessions where they openly share experiences with people who have also undergone the same experience.

Ithink the correct answer would be that since the disease is passed by a hand shake and can be cured with antibiotics that it could be an infection. an example could be that once when i was working in a bush camp, i got blood poisoning from blood blisters that got infected. our cook did not wash his hands after going to the bathroom and he passed staphyloccus on to the crew he fed. one other person also got a bad similar infection on the side of his face. i had to be rescued by helicopter and taken to the hospital so i wouldn't die!
