Ever since RC cannabinoids came out, I've been curious about this. Couldn't some unscrupulous asshat make his hash/weed more "potent" by mixing it with RC's? I've certainly had cheap hash that had a bad enough taste to cover a tiny amount of RC chemical taste.
Would there even be a way to test for this? I'd image that hash is already a big soup of various cannabinoids, figuring which ones don't belong sounds like a tricky job.
Absolutely but not worth it. Ive never heard of it though. Rc cannaboids are strong and easily felt if your a regular user of marijuana. The difference between thc and synthetics is easy to discern, for me at least. So if you are withdrawling from your vendors flowers you are smoking synthetics.
