Nicotine sulfate is still a powerful and effective insecticide. THC in combination with the synergistic chemicals in marijuana have NO “direct” lethality, and great medical use. NO it is not correct to compare tobacco and marijuana “contents”. BTW: coal fired plants put out far more carcinogens around the world than tobacco, at least to the masses. But RJR and PM have done their best to hook people around the world on tobacco, starting at age 3 or so in the third world.
Which, nicotine IS addictive chemically, while marijuana is NOT! (psychological addiction is NOT the same thing!)
