Definitely. Since the same compounds are formed in meat during cooking, so there is a curious evolutionary correlation: did the first humans harnessing fire and cooking meat do so for the psychoactive effects? The implications also touch demographics, since humans have great variance in the activity of their MAO-A and MAO-B genes. People who get easily addicted to smoke flavoured food, coffee and/or tobacco may simply have inherited a high-activity MAO gene that they are trying to compensate for.
