It's shameful how often this happens with unscrupulous businesses. In San Diego I was talking to a bud tender and at her previous job she said the owner would sometimes buy really huge batches of mid-grade bud, then split it up into different piles and label each one differently. So some of the bud would be labeled "Gorilla Glue #4" and some would be "Blue Dream" but it was all actually the same bud. I'm pretty sure this happened to me once before. I purchased two different strains from a dispensary, but I'm 99.9% sure they were actually the same strain from the same grower. They were both cured really oddly, and I've never seen bud that looked like that from a dispensary before or since. I feel pretty certain it was the same batch just labeled differently.
