Cocaine

Cocaine is a stimulant that gives a euphoric high for 30 minutes to 2 hours. Cocaine when ingested provides a numbing sensation. You can also sometimes feel the numbing sensation on your fingers.
Do not mix with alcohol for it may cause overdose. The high mainly consists of increased awareness and a feeling of intense well being. Some get violent under the usage of cocaine.
Cocaine is usually snorted but sometimes injected. I wouldn't recommend it to anyone.
