Mycotoxins in lichens?

Here on the New England Tablelands (NSW) we have a very common foliose, 
lime green-coloured lichen that often completely covers introduced 
plants such as plum trees.  A local naturopath has suggested using this 
lichen as a "healthy" tobacco substitute, as I'm trying to give up 
smoking.  However, I'm rather sceptic, as I'm aware many fungi contain 
toxic metabolites.  Is anyone aware of lichens producing anything that 
would make smoking them potentially hazardous?
