> If I want a joint

Just give up the idea of joints. You don't have to conform to weed culture or tradition (or marketing) to smoke weed. As an act, smoking isn't particularly pleasurable (although I have to admit that smoke is mildly entertaining.) How about taking 2-3 hits from a water pipe, vape, or just an old-school pipe, and spending the rest of the night drinking something you enjoy? Have some tea instead of smoking more pot. Popcorn is very good, and fairly low-calorie.

Popcorn is actually really calorific

But anyway I like joints and so do a lot of people, I don’t see this as a solution

yeah very high percentage THC in nearly every variant of weed these days, for me having a joint with tiny sprinkles of weed completely fucks me up, I just choose to have hash with lower THC percentage, plus hash tastes nice. I think that the really strong stuff should be for medical patients, or people with really high tolerance, because for a teenager that doesn't know what it can do, it can really ruin them if they keep having it, especially since the strong stuff is more addictive aswell.

In most countries we don’t have such freedom of choice, so we only get the high THc stuff

Everyone I know who wants the lite beer of weed has turned to home growing. I wish I lived in a state that allowed me to do that without fear.
