“It has all the same carcinogens as tobacco.”
Wrong. Tobacco companies add nitrates and formaldehyde in cigarettes. Also the smoke particles are much larger in weed smoke. The cilia in the lungs can remove them. Tobacco particles are much smaller and lodge between cilia so they cannot remove them. Eventually it causes dead spots in the lung tissue. You don’t see that with weed smoke. Nor do you see lung cancer at the rate you do with cigaretttes.
