I'm from the Netherlands as well and I'm interested in this thread. I've tried CBD in pills once, from a trustworthy seller, a long time ago. It helped,to get me out of deep, acute psychosis, but only in very high doses. I tried smaller doses before and they didn't help. I can mostly remember it made me a bit "dreamy" (dromerig).
I also used oil once from a somewhat shabby "coffeeshop" and somehow this had a really different effect... I ended up all hyped up, speedy, not capable of falling asleep all night, totally panicked and even more paranoid than before.
I'd like to grow CBD rich weed myself and use it, but I'm not really sure where to start. Buying pills or oil would be too expensive.
