I don't eat meat because it causes suffering in another. Plants have no concept of pain without a brain, nervous system or even nerve endings. So to me, the question becomes if the lab grown meat was ever attached to a brain that could feel suffering.

Now as far i understand it, lab grown meat isn't nessecarily grown in isolation from a cow. But in a solution primarily compromised of blood extracted from living cows. That's without question better than killing a creature, buuuuuuut we all know that when profits are involved the health of a animal is not prioritized.

So it really depends, while I don't miss meat, once lab grown becomes widely available I'll make my choice depending on the exact process of how it reached the grocery store.
