Hi pbrown, and welcome to NT. I don't have an answer for you. I know that smoking can cause pn. It would stand to reason that smoking cannibis could cause it in some sensitive individuals. Some people are more sensitive to some elements than others. What is poison to you, might not be to others. I have a friend who ended up with pn from drinking alcohol in small amounts.

We have a great PN forum, and you might want to check out our Vitamins and Nutrients forum to help you deal with the pn.

Take care, and hope to see you around the boards.
