You can get organic tobacco's and chew or smoke. Look up the base molecule of the B vitamin Niacin.
It also cleared the voices in a friend's head who was diagnosed with schizophrenia. But the doctors kept pushing him psycho meds. He died.
Many of us who smoke or chew use it to keep our focus. Some call it ADD or ADHD.
It is also one of the oldest insecticide compounds known.
A friend quit some years back and developed asthma. His doc told him that is common as something in the smoke keeps asthma under control. Now he carries steroid inhalers. Oh well
I have two brother's that lost teeth due to chewing tobacco.
I don't know why it happens but it is not good for your teeth.
They over done it. Some guys will stuff 1/2 a can in and let it there all day and sometimes sleep with it.
Been popping in a M&M Peanut size pinch 3 or 4 times a day for over 30 years. No gum or tooth problems
The poison is in the dose.
