I just posted on my grow journal, about this VERY thing! Everything in todays genetics are so convoluted, they are hundreds of strains deep! Breeding for high THC, seems to be making everything like moonshine. It will get you fucked up, but the buzz is similar on most of them. I get a more, quick, heavy buzz from newer strains.
I like the slow creep and 15 minutes later, "what the hell did I just do?"
I've gotten high as hell, from 17%-20% THC strains. I feel like I was higher in the 90s than I've been these past few decades.
It's not tolerance, I smoked some Columbian land race recently and it fucked me up!
