If oral THC is not working, try vaping the THC.
We now have good data on about 150 results and some really interesting stuff is shaking down.
At least five folks get very little results from THC that they take by mouth, but they get GREAT results from THC that they vape. This works out to around 7% of folks who respond to THC at all.
There is an explanation for this.
It turns out that when you inhale THC, you are getting the delta-9-tetrahydrocannabinol directly into your bloodstream. This is the chemical that your brain/body see when medical marijuana is vaped.
However, when you EAT your THC product, your liver transforms the eaten THC into 11-hydroxy-delta-9-tetrahydrocannabinol as the predominant chemical that your brain/body see.
And it turns out that about 1/15 folks respond well to vaping delta-9-THC but don't respond well to its 11-hydroxy-THC cousin they get from eating THC.
All this stuff is in progress, so Watch This Space.
