Poly Drug Use
This simple means that someone is using more than one drug at the same time.
For example Cocaine and Alcohol are widely used and reported at the moment. The
cocaine will keep the user drinking and alert for longer, but then
creates a separate drug as the body mixes them together creating
coca-ethanol. Medical reports suggest that coca-ethanol is damaging to
internal organs: liver, kidneys, heart and lungs and increases the
dangers of using both drugs on their own.
Another example is Speedball or Snowballing, this is when cocaine and heroin are injected together, this is very dangerous and can be fatal.
Cannabis and alcohol are both drug's that seem to be used with most other drugs.
