I found out a couple things smoking cannabis while not smoking ciggs...

1...ciggs stain yur teeth,pot does not...

I stopped smoking ciggs 2 years ago and started smoking pot about 6 months ago... My teeth are still getting whiter,2 whole shades according to my dentist...

2... I continue to get healthier,no more chest pains,I had worse chest pain when I started smoking pot 6 months ago...
