It's not really a question of being judgemental is it now.
A careful reading of your posts elicits the following information:
You must be in your early to mid twenties. (University six years ago).
You took drugs of one sort or another at some time while at university.(Many of us did.)
You do not want to 'do' drugs. (Most of us don't.)
You make distinctions as to what you consider to be drugs, or at the least, acceptable druggy substances.
You make distinctions as to what is a reasonable or suitable quantity of drug to ingest.
You had too much to drink and took drugs. You really neither consider that what you took was a drug nor that you took too much.
You knew what you were doing.
Please excuse some who might cast a jaundiced eye on such an approach to any sort of mind altering substance on the part of crew with whom they might have to work. There is nothing bitchy about the conclusions which one might come to, based upon your own statements.
Res ipsa loquitur.

I had a chat about this very subject not so long ago with an AME. He stated that any hashish ingestion could be detected for up to six weeks, at least.
He may be wrong, of course. I should think it depends upon the sensitivity of the test equipment that might be used.
I'll now put my Sherlock Holmes hat to one side and ignoring the Judge Jeffries black cap pretend that I am the head, whatever it may be called, cabin services supervisor.
