I've grown out a clone of Harlequin and smoked it and it was a very unique "high".
I knew about the high CBD content as my lil sister gave me the clone, she gets paranoid from high THC but loves the Harlequin high.
I equate it to a very clear headed high if you can even call it that, more like your floating a bit, almost numb. Seems to be very good for pain relief and the funny thing was right after I smoked it for the first time, my parents came over 15 minutes later and my wife & I were amazed after they left at how we both seemed to be able to forget we even smoked, truly a non-psychoactive/non-paranoid high.
I think this is this future of more socially acceptable cannabis as Israel has been able to create a strain that registers around 15% CBD with less than half a % of THC.
In my opinion, this could get all of the patients & users who are hesitant to smoke/medicate with marijuana because of the stigma of "getting high", into it and then once they realize all the medicinal benefits, the world will be up in smoke and Big Pharma free!
A man can dream can't he?
