It actually appears to be quite prevalent these days. I told my friends/coworkers about it and it seems as though I'm not the only one who encountered trees with lead in them. A few people are going to go back and look at their tree because they never even thought to look for something like that. The warning is printed so small and inconspicuously. Approx 60% of the people I have talked to had to return trees or didn't buy them because of lead.
