I'm interested in other's ideas on how they would describe the spectrum from poly drug user to abuser. I'll define two obvious ends of the spectrum...

User: uses a stim one weekend, a month later drops MDMA, a month later drops acid, a month later does a single perc pill a month later starts over on this four month schedule doing each drug only 3x a year. I think this obviously would qualify as a poly drug user, but not an abuser

Abuser: is taking something every single day, can't stand being sober, takes whatever they can get to not be sober. Continue doing things even after obvious negative side effects kick in like blood in urine from too much dissos or septal hole after too much blow.

So, my questions is, can you give me an example of a point where you would draw the line between definitely OK user and questionable user. This seems like the line you want to avoid crossing if you want to be extra safe. I know its going to be different for everybody, but I think this will be an interesting discussion. Please don't post things like "there is no safe poly drug use" because this question assumes there is.
