This thread is filled with fail...
JWH is no joke. Check out the [MEGA] Syth thread here in CD. For reasons why not to smoke these pre-packaged blends, see the K2 Ruined My Life thread. The problem besides the obvious over expense with them, is you have NO idea what is being put on it (which syth? Are they clean? Are they waste chemical?) or even what plant you are smoking.
Get pure JWH and make your own blends. It's very simple. Again, all this info has been covered several, several times over and over again.
Oral JWH works just fine without need to cook or even prepare, you can eat it right out of the bag and drink it down with some water - it's tasteless.
