Ok I may be delusional but I didn't get a headache and I felt a reaction for a short time, nothing long lasting, weak but present. I'm on neurontin for neuropathy and it is great for managing withdrawal problems with cannabis. It also feels a little like thc so maybe I confused the feeling of neurontin for thc. Anyhow I completely ran out of wax etc. for the month a week ago so I don't have any sort of semi-permanent buzz from heavy use. I really think I felt a reaction. Even if there was no effect the taste was not harsh, the aftertaste was pleasant too. That is rare for me, I guess it augurs well. The ones in the 3 gallon pots are the 5 week old teens I got for free because they were stunted. I tied them down and I've had them for a week.
