Extracted from coca leaves, cocaine was originally developed as a painkiller. It is most often sniffed, with the powder absorbed into the bloodstream through the nasal tissues. It can also be ingested or rubbed into the gums.
To more rapidly absorb the drug into the body, abusers inject it, but this substantially increases the risk of overdose. Inhaling it as smoke or vapor speeds absorption with less health risk than injection.
“You believe that coke will increase your perceptions, that it will allow you to surpass yourself, that you will be able to control things. It’s bloody nonsense. After a while you don’t pay your bills anymore, you don’t wash yourself anymore, you give up your friends, your family. You will become defenseless and alone.” —Nigel
