But if you do become addicted to nicotine, and are one of the people with a high propensity for nicotine addiction, you're fucked. It's one of the most challenging addictions to quit, as we all know. Is this a risk you want to take for some mild stimulation? As a former smoker, I can only believe that anyone who takes this risk does not fully appreciate the consequences. The exception might be people who have consumed nicotine on and off but have never had addictive tendencies. Those people definitely exist, but it still seems like a risky thing to assume about yourself since being wrong could be life altering.
I also take exception to the articles emphasis that moving on to cigarettes is the only real risk. Yes, that's where the majority of the health problems come from. But don't underestimate the negative consequences of a physical addiction, even one that does not lead to health problems. It is not fun to be addicted to anything that contorts your body and mind outside of your control.
