The Dangers of Smoking and Injecting Cocaine

Cocaine, a stimulant, might harm an individual and is very addictive, and overdosing on this drug might kill an individual.1,2

An individual might snort powder, smoke crack (known as “freebase cocaine”, “cocaine base”, and “crack cocaine” as well), inject powder that’s been dissolved, or use cocaine via a different way.1,3 Compared to snorting cocaine, smoking or injecting it can yield a more powerful, faster, and more brief high.1

If an individual smokes it, it might trigger a high that endures for less than 10 minutes; if an individual snorts it, it might trigger a high that continues for half an hour.1

Frequently, cocaine-using individuals use the stimulant via using it multiple times, using bigger and bigger amounts, in a brief period, which is known as a “binge”.1

An individual could experience a “rush” – a powerful, quickly-occurring euphoria.3 An individual might become anxious, paranoid, restless, alert, irritable, and/or energetic.1,3,4

Cocaine is able to be utilized medically in America, but this is uncommon.1,3
