marijuana almost killed me, because I am allergic on it, I lost a lot of weight

Do you think people who are allergic to marijuana lose all their weight until eventually death. This is what happened to me every time I get addicted to it, and almost died 3 times and this is the only time I knew it was from smoking the stuff. I quit 10 days ago, and still no weight gain and my skinny bones hurt and it's getting really hard to cope.
