Pulmonary specialist and Federal Government
researcher from UCLA Geffen School of
Medicine finds that marijuana does not cause
lung cancer in his study on the effects of
cannabis and the lungs. Results of this
study are discussed for the first time. If
you agree that cannabis should be legal,
write a letter to your congressperson and
tell them to legalize it! Tags :videosoriginal420marijuanapeopledoctormedicalresearchcannabislungsUCLAcancer
