Never had it, yet anyway. But I was intrigued by your story Tyler. If I'm reading right, you said some guys got it because you burnt some? That's crazy.
My understanding is that you don't even have to touch it. Apparrently the first time you come in contact with it you should get no reaction but you DO build up a sensitivity to it. The next time you come in contact with the oils or resins, even on some other object, you will develop a reaction.
