It is GM hemp not dope. As for the reference to THC lowered pollen, I am speculating. Think about the amount of dope grown in certain areas, dose those areas with no THC pollen for a few years and it would be bad news. Remember that the total weight of the all the indoor crops in a given year is miniscule compared to the amounts produced outdoors. The genepool could take hits with other GM methods but I don't want to describe any the bad guys have not thought about already. I will try and find a link to the paper and post it. It was a thesis.
