Good example of why lab numbers are useless. The entourage effect is what makes the high. Numbers are low, yet you are ripped, proof is in the bowl.
Most wrecked I've ever been off smoking herbs was a 8-10% Vietnam Sativa. It was like acid. Looked like hay and wouldnt have any impressive numbers but by God you would be fucked up for half a day. Too much too much lol
Of course, any issues with the grow will affect the final outcome.
