Im in Ky, and for the last 2 years all kinds of Cali stuff has been coming in, and its loaded with sprayed on terpenes, or something. Sometimes its so strong, and sour, for me its unsmokable, and in reality I only smoked it 2 times because it was readily apparent it had been tampered with.
Its all at best C grade compared to what is locally grow. No comparison on which is best.
Also the shit they use to strip terpenes I bet has never been tested as to what it does to the lungs when you smoke it.
And I believe the Terpenes themselves are oil based, it could be that when vaporized, they can reform as oil, back on the lungs. And then you have people concentrating them ect???
Bad things were never really reported when people were just smoking the buds, hash ect.
All this shit is getting ahead of research, and the public are their test lab rats. Not me. Just give me buds, or hash. If your shits not strong enough, then you've got the wrong weed.
