no one is allergic to posion ivy. poison ivy is -poisonous- hence the name . . . and its poisonous to everyone hence the no one being allergic to it comment.

could be that the longdongberries you ate were/are poisonous. know anyone else that eats them and doesnt get sick?

the tobacco juice may not be posionous per se but its not exactly V8 if you know what i mean. plus, theres pure nicotine and tobacco in there which is like injecting TIDE into your blood. lol
