@tripu When drinking alcohol and using cocaine, cocaethylene is made in the liver through a trans-esterification reaction. Sometimes it's really important to point out the alcohol and or cocaine as they both cause bad reactions with commonly used drugs. A Beta Blocker and cocaine is really bad. Alcohol and benzos cause a kindling effect.
Alcohol also has the ability to be completely eliminated from the body and not just infinitesimally close to being eliminated. See halflife and ask Mathematics or Physics Department.

All that is interesting, but one can explain it referring to “alcohol and other drugs”, instead of “alcohol and drugs”, which is misleading. Right? That's my point.
