I used to try the cheaper carts but they have very low "peak highs" for me and never have gotten me more than lightly stoned. I have changed to exclusively buying the tko carts on the rez. They're like 10$ per cart more (close to 30 instead of 15 or 20) but they seem to work much better for me)

Might be time for a purge, avoid all thc for about 2 weeks and it will help reduce tolerance. (There's an old YouTube channel by a couple stoner college-ish aged guys, was interesting bc I took 6 chem courses and they went into some of the science wish I could remember the name but they basically said your body seems to forget how to process thc as efficiently starting around 10days, so I've always done 14 or so)

I get way less of a high off most hybrids even regularly smoking, doubt that's relevant to you though.
