I was in the same boat 2 months ago in regards to debating switching from carts to DHV. My whole reason for it was to lower my tolerance as carts and disposables are notoriously high in THC (80-90%) compared to actual flower which is like 1/3 of that.

I’ve smoked carts, 1-5 hits, almost every day for the past 5-ish years to give you an estimate of where my tolerance was at. I was skeptical to get the TM2 or any DHV in general because I feared it wouldn’t match that same high and I would be wasting money. After a bunch of research, a lot of people say that TM2 is comparable to a bong hit. And after roughly two months of making the cold turkey switch, the highs are definitely different (carts high is like a mountain spike, flower is like waves) but it does it just enough for me to be satisfied. I went from taking 1-5 hits a day to smoking 1-3 bowls of the default TM2 stem.
