Well... though ingenious, this idea wont work.
The high from ingesting weed is weaker then the high from vaporizing/smoking because the absortion of the active substances (THC/CBD/whatever) of weed is far slower when the weed is ingested.
When you smoke/vaporize the weed, the active substances goes directly from your lungs to the bloodstream, and then to the brain. It happens in a few minutes, so very soon all the active substances you vaporized/smoked already are into your brain, making you high.
But when you ingest the weed, it must be digested, and then the active substances must pass through parts of the the digestive system until it reaches the bloodstream. It takes far longer (hours), and its very gradual. The active substances are delivered to the bloodstream very slowly, so the amount present in the bloodstream is far smaller than if you had smoked it, thus making the high far weaker (but longer though).
So, unfortunately, if you want to get the highest with the smallest amount of weed, the only way to do it is smoking/vaporizing. :jointsmile::thumbsup:
