from what I gather... JWH-018 is very sativa like with properties of psychedelics but is very dose responsive and causes anxiety (not good because I have an anxiety disorder). While JWH-073 seems more relaxing and indica like without the complete stoning and near no anxiety but requires a higher dose.
I'd say the opposite is true for me. 018 I find very heavy going, not at all psychedelic and very good at producing mega-anxiety. Certainly gets you incredibly stoned though. 073 I find very light and upbeat, fairly euphoric and much closer to a "trippy weed" effect. I have no intention of buying 018 again even though it works out so cheaply cos it's just not very enjoyable for me and it's also blocked my favourite pipe solid with rock hard gunk. YMMV and all that

Not sampled 200 yet and don't know enough about it to know if it appeals so am waiting for some reports to come in from my fellow human guinea pigs. Suspect I'll acquire some at some point just because I can't resist a new drug :D
PS: Nice stickjob on the new B&D thread, Uniter :D
