An interesting turning point for all of these is the recent discovery that tobacco smoke contains more chemicals that may be psychoactive and addictive. Nicotine is not the only one. But scientists are not sure what it is. Today's neuro imaging technology shows that MAO decreases when someone smokes. MAO is a monoamine oxidase used by the body to degrade dopamine. Even if MAO decreases, the dopamine level remains high and leads to poisoning
