Quantity, it's said, has a quality all its own. Anyone who wants to look at their personal unproblematic weed use and conclude that it's totally, universally impossible for today's weed concentrates to be a problem for anyone really isn't thinking straight. There is a difference between concentrates and flower. Once you're habitually using something that's 50%+ THC, "normal" weed just doesn't cut it anymore. You need to start upping the ante just to feel high at all. People call this "tolerance" but IMO that word obscures what's actually happening. Namely, you can only put so many feel-good chemicals in the human brain before you hit diminishing returns. Trying to keep the good times rolling may cause you to blow past your body's ability to metabolize the chemicals away without consequences. I've been a stoner for 12+ years and have had to learn my limits the hard way. I really feel for the girl in this article, and anyone else who's struggling with their weed use in a culture that repeatedly insists there is "no unsafe dose."
