Psychoactive drugs: chemical substances acting on the cns that alter mood, perception, memory, or behaviour. Entheogens are usually used within religions o. In high enough concentrations, nicotine can be hallucinogenic. o. In their ceremonies, they are doing it in a group, so they are taking in it from their cigarettes and from their peers blowing it out. Sinuses (in your nose) and gums have a very thin membrane and nicotine can pass easily and go into your blood: which is why people chew or snort it. Plants naturally use caffeine as a pesticide, by paralyzing the insect. Chewing on botanicals with caffeine is very old. Discovered coffee beans by observing the change in behaviour animals exhibited when they ate the botanical plants. Only actually come from 2 types of leaves. The different tastes arise from the baking methods. But these different methods do not alter the caffeine content. Green tea does not have less caffeine than black tea.
