> THC is destroying mitochondria like nothing else...

Really? I've never heard that. What source did you learn this from?

I tend to eat weed before running and have for 20ish years. If it really did destroy mitochondria then I'd expect it would show up in my vo2 max or some other measurable health stat.

I'm slightly concerned but given that this is the first time I've heard this, I'm not too worried about it.

I personally believe cannabis + exercise is the most glorious thing on this planet. I've been using it primarily as an ergogenic for some time now, simply fabulous.

If THC was especially good at destroying mitochondria we'd be seeing lots of cannabis users with cases of necrotic tissue due to cells being unable to maintain their metabolism.
