then it's easiest to go to a store and buy some to try out. Easy and relatively cheap.
For those who need doses stronger than a given state will allow without an RX, or for those living in states that don't allow recreational use (RX only), then obviously getting the card is the way to go. Last I heard it cost a few hundred dollars, in OR at least, so just going to the store works better for most.
PS, I agree the "real stuff" can cause unwanted side effects (paranoia, or "feeling scared" as you put it). One way around that is that if you can find strains that are from sativa (as opposed to indica), that's supposed to provide more of a feeling of well-being. From what I'm told.
The other thing I'm told (Oregon "bud-tenders" are extremely helpful with information), straight CBD is not as effective (therapeutically) as CBD with a HINT of THC, which acts as a kind of "booster". I've tried this out and find it to be true. I like the cream for localized pain, but for anxiety, tincture is kind of amazing.
