I'm listening to your episode with Dr. Cowan and there are a few health related items my wife has found that I think you and your family will find as useful resources.
1) alter.systems - this is an AI trained on ALL medical data. Traditional and alternative. My wife has cancer and has shrunk her tumor by 68% in ~9 months. Alter has helped her time supplements, identified suitable treatments and help review lab results. It's pretty amazing. This is how you can optimize what you are doing with your smoking.
2) Weston A Price Foundation - I think you may already be on this train but it's been great for us. Raw dairy, healthy meat, organ meats, fermented foods, etc.
3) Sue Becker's book "The Essential Home-Ground Flour Book" - You can find it on Amazon and elsewhere. It turns out that bread made from fresh milled flour is a completely different food than any other bread. High in protein, rich in nutrients and often tolerated by people that normally have gluten issues. It does take a bit of work but it is totally worth it. My wife is on a keto diet due to the cancer and she can still eat 2 slices of her bread with no issues and six pack abs.
All the best
