I am not sure how much an ounce would make.
Per pound of high quality trim and small popcorn buds you can get almost 2 ounces of final product.
Lower quality trim, greenhouse and outdoor with no small buds will give you up to 1 ounce.
Never tired the glass Turkey Baster before. I know R2-D3 mentioned it before. Looks like a good, proper way to do small personal runs.
As far as the "spice-like" high comparison - I have seen seen people (my roommate) have severe panic attacks after doing a hit out of a 2 foot Moebius Dabber Rig.
I have also seen people turn white and pass out. A lot of times at a harcore oil rig sesh, 20 minutes into the session half the people are nodded out and drooling on themselves.
This is usually the first few time people do it. You get used to it after repeated uses.
It def has that "head-crushing" effect, and although it isn't AS rushy as "spice", each hit will give you head-rushes and make you see "stars" if you stand up too quickly.
It also gives you that super intense cottonmouth like spice, and lasts forever regardless of how much water you drink.
If you notice in the video, one of the people mentions that he no longer smokes pure weed anymore because it doesn't work for him due to his constant "dabbing".
A couple of my friends say the same thing... and when I pass them a joint outside a club or at a party they don't even get excited or care about smoking.
Also, it is an expensive habit. Clubs sell it for $25-40 per 1/2 gram. My buddies will sell it to me direct at $20 per gram. Ouch !
