In the work presented here, the author shares research from collecting reports from the New Jersey State laboratory (the Department of Health’s Environmental and Chemical Laboratory Services), which has conducted testing for the state’s medicinal program. He documented an average variance of 20% in potency levels from different samples of the same test lot.

A large data set from Washington (140,000 flower samples) is scrutinized here for evidence of consistently propagated strains with higher than a 2-to-1 ratio.
