I never ever said that alcohol is nothing to worry about. I just said that the liver heals better than the brain Please refrain from putting word in my mouth (or anyone) in the future.

And if your next point is "yeah but we know nothing about the long lasting effects after your stop", nature has you covered : https://www.nature.com/articles/npp201744

From the Abstract: "Future longitudinal studies could help determine whether cannabis use contributes to these observed shape differences or whether they are biomarkers of a vulnerability to the effects of cannabis that predate its misuse."

Also, the liver doesn't "heal better" than the brain. If anything, the problem is that Cirrhosis isn't really detected until too late. I would counter that more things cause brain damage than liver damage.

Finally, the last study you point to references two other studies that found OPPOSITE results in its discussion, so trying to say that is the definitive answer is scientifically disingenuous.

Your data doesn't even help your cause dude. It just shows that further research is needed before going out and making "case closed" proclamations.

Nature seems to cover you for 3 days after smoking, but what about longer times?
