I've not heard of this before. cbd, cbn are still pretty prevalent cannabinoids. Especially in the indica's I believe. Thc works best alongside all the other cannabinoids, meaning that they all combine to give a particular effect. Thc will actually turn into cbd and cbn, I'm sure that's what the clouding (of thc crystal) is. If you wanted to avoid cbd and cbn, you need to harvest earlier. Personally, I like being that mashed I can hardly move. Although I do like the trippy weed (sativa) too sometimes. In fact, I'm growing grapefruit right now.
Just got some la confidential seeds, but they are x'd with some mystery haze. Also got some biddy's girl, anyone ever heard of these?
I don't suffer the munchies anymore either. Only very rarely, I suppose it comes from eating healthily. I'm very fickle about my food, which is why I taught myself to cook.
