Nicotine. I've never smoked but I started experimenting with nicotine lozenges and they are great. It helps my concentrations and focus a lot. So far I've found minimal addictiveness and no negative effects but obviously that varies by person and you should be careful. I've never smoked and smoking seems to be kind to many of the negative effects of nicotine.

Just adding that I really don't find nicotine all that addictive either. I find other common drugs extremely addicting and hard to stop in comparison (namely: caffiene). my naive opinion is that smoking ends up more addictive due to the habitual nature versus the nicotine content of cigarettes.

I quit smoking by reading a book[1] about how to quit smoking, which basically said the same thing. Nicotine is not addictive, a true addiction will cause withdrawal symptoms like alcoholics can die if they quit drinking too fast.

While reading that book, I just stopped smoking cold turkey. I still get cravings every once in awhile especially when I see other people smoking but easy to control now.
