It most definitely is not going to be infection, I mean unless your injecting it in your veins. Technically any chemical, I'm guessing at least, can probably play a role in getting cancer. I'm not sure about bone loss. My first and final answer would have to be a coma. You could get paralyzed and trip out also. I'm pretty sure it shuts down a nerve system, and that leaves the person completely unable to fight back and leaves you completely vulnerable and more or less stupid. I think it has been known to affect every one in a different way.
If you take certain drug in a beverage thats bad as well it can slowly turn off you nerve system and organ function which can cause you to go in a coma for a long time.
