Information about the Effects & Risks of Smoking:

Ammonia

This colourless toxic gas has a rather strong odour. In cigarettes, its main role is to augment the impact that nicotine produces. Other than cigarettes, ammonia is commonly used in fertilizers and various household cleaning products. Ammonia works in increasing nicotine’s impact through ‘free basing’, and this is akin to the process that heightens the effects of cocaine.
