I work at a dispensary in the processing side of things. I get to talk to vendors and see their new and old products ALL the time. I can tell you that good growers for dispensaries are few and far between. We regularly get pounds of absolute bullshit, sell it in half ounces for $70-$80 a pop.
The testing, at least in my state, is always full of shit. Recently we received some prepacked 8ths from a company, and that bud was supposedly testing at 37% THC. Thats a croc of shit. We have infused weed with lower testing than that. To add insult to injury, the weed doesnt even look that great.
Companies have found tons of shortcuts and other ways to maximize profits while leaving the quality of the buds in the dust. My brother in law is an agricultural inspector for the state we live in. One of his coworkers recently did an audit on a BIG commercial grow out here. Well in the audit, they found the company spraying certain pesticides on the plants, knowing the testinf facilities dont test for those types of pesticides! So people are consuming contaminated "medical products"!!!
The industry needs a kick in the ass. Mainly the rich buttholes diving in without the slightest knowledge of anything involving cannabis. Only business knowledge. Its not a good situation. Id recommend growing your own if you wanna be able to trust it, or go with the highest quality companies you can find (alien labs is great where i live).
