According to research from the Los Angeles Biomedical Research Institute, the effects of smoking can be passed on to future generations.

(The study was carried out on rats, but a rat’s physiology is sufficiently similar to a human’s to suspect the same thing may be true in Homo sapiens. In a nutshell, Dr Rehan showed that if pregnant rats are exposed to nicotine, not only will their offspring develop asthma induced by nicotine, so will the offspring of those offspring, neither of whom had been directly exposed to nicotine.)
