Tylenol in high doses bad for your liver. I would recommend no more than 3,000mg per day for Weezer. 4,000mg is the LD50. (Lethal dose for 50%) but it takes a long time to accumulate that much damage. Only need 11% of your liver for normal bodily function. That’s why alcoholics can go so long before they get cirrhosis.
Looking at all of the redundancies and incredible amount of abuse the human body can suffer before failure makes me a believer that God is an engineer. Our wonderful body is so over engineered that I am amazed by how we are put together. No way is this evolution.
With that being said, I would implore you to make a pros/cons list for vaping. Trying to get my son to stop (using medical facts) was truly eye opening to me. Until I looked, I had no idea how many cancers that nicotine alone is associated with. It is a strong cardiotoxic substance. It affects blood vessels. It single handedly can stop the healing function of your body. (Why tobacco users look so much older) No ability to heal from life's daily trauma. Then add to that the fact that our lungs are not designed to be coated in oil (vape delivery system). It hasn’t been around long enough to to know the long term consequences. Why be on the forefront of people who will find out in 15-20 years…
You seem like a good person. I will miss you.
