Does the trinity allow smoking, can you smoke?
Not really as there is hundreds of micro organisms inside tobacco as they came from water. "Do to others as you want done to you". This means you should limit to drinking and eating only. Smoking is a leisure not a necessity, a guilty pleasure you could say. Hundreds of organisms will be screaming as they are burned alive by a lit cigarette or lit pipe. Though pipe is a much quicker way of sending a demon back to heaven.
Plus everyone knows you might get cancer by smoking, so basically is it not you're chancing suicide by getting a painful death getting cancer.
You are allowed to vape as there is allowance of having a hot tea or coffee, its just heating water, its not like slow burning melting fire, so if you've a nervous disposition or can't kick the habit of smoking, then Jah understands and will not judge if you vape, Ephesians 2:4-5 – “But God, who is rich in mercy, out of the great love with which he loved us, even when we were dead through our trespasses, made us alive together with Christ — by grace you have been saved".
