I have several friends that have been smoking for decades. I introduced them to vaping, and they never went back! Give it a try. You still get your nicotine fix, so the cravings aren't an issue, and you aren't burning anything and putting all the dangerous particulate and carcinogens in your lungs. Nicotine can be toxic in large doses, but the real danger is burning anything and inhaling it. Vaporizing is simply atomized liquid which is considerably safer.
