I think you're right. I've always wondered why they don't water down GHB to be the equivalent of a low ABV drink. The only scary thing about GHB is its relative potency to volume. It's honestly a wonderful drug.
I tried it once but didn't feel anything -- it would be nice to give it another go.
I agree it is a nice drug but one friend of mine did have his family stage an intervention because of his abuse of it.
