You confuse depression with being mildly irritated, don't. Depression is real and is not caused by running out of anything. Also using every day doesn't 'lose the magic' as you claim, in fact I suspect you don't know what you're talking about and are a reader/contributor to askfrank, a disinformation site run by the UK government and packed with utter nonsense.
However, massive overuse can lead to depression, this is already well known and written about. I have only known one person who suffered from cannabis induced depression, using huge amounts, a virtual chain smoker, who became increasingly depressed over time and incresed consumption accordingly. Slippery slope. But most regular users don't run any risk, if only because to use so much you have to be able to afford it.
