i can kinda see that cbd assertion, as i was at my most creative when i was a pothead in my late teens, and it was a time when access was limited to low quality stuff that was mostly comprised of cannabinoids other than thc and full of stems and seeds
the few times i've had the opportunity to try the high octane stuff that is legal in most states, i kinda lose any ambition and just go with the flow of whatever is happening around me
