Well 2 things come my mind .If you use codeine
for long time your tolerance will go up and you will have to take more and more to get high.
Other think is drug
dealers where they get the drugs
and how it is made .Well normally codeine
or oxycodone after taking pills the euphoria
should be awesome and yes it will give you a drunk like state.The drunk like state and euphoria is why people get so hooked on codeine or oxycodone .
Alot of people love codeine
or oxycodone do to it making them very sedating , overly-calming effect ,drunk like state ,slurred speech, staggering ,poor judgment,very calm and relaxed
Well sedatives or tranquilizer is a substance that induces sedation and slurred speech, staggering ,poor judgment, and slow movment.They provide calming sedative effects and people get hooked on this.
Well codeine or oxycodone is like this but has euphoria feel has not all sedatives or tranquilizer will give you a euphoria feel .
I also think alot has to do where one gets the drug the drug dealer and where he gets it from.And all these drugs are very addicting.
