Say I'm in my late 70's, have been smoking since the '60's. Have a MM license, so I can grow and buy legally. That said, I can walk into a dispensary, find the highest tested THC and do not get high like the old days. I can drink coffee and wont keep me away. Sativa does.
Having a back injury, one leg has no tap at the knee that can spring out and hit you in the balls, but is like a dead cylinder with zero compression, zero movement. Long standing begins to signal pain, but one hit of the ruderalis {CBD} subsides the ache within minutes if not seconds.
Anything in the high percentage of THC testing shows no out in space buzzed, wild thoughts, hard to sleep, all that shit, means shit. I go out of state for days on end, I have no panic attack, or addiction for it, nor even think about it.
It's more a head game over matter. Smoked cigs and quit cold turkey. Got so drunk mixing beer/wine, threw up in the street sitting on a curb celebrating the 4th back in the early '70's, I never got drunk or even felt a buzz from that day on.
Probably have to change up strains to catch a high, but I'm not into a buzz, but for pain relief. Piss my money away for different strains to chase for a high? Not me.
