Sorry I’m working, haven’t read all the posts.
Have you ever taken something like anxiety pills ?
So (it’s a very simplistic explanation), but you body builds up a tolerance level for it. So what gave you a high for a while, at some point your body will say ‘well that’s fine and all, but I’m used to this, I need a bit more now’.
And that’s how it increases and increases.
Another comparison, although it’s not the best, would be like coffee.
Or smoking : you rarely see people decreasing their amount, it’s their brain saying ok I’ve got used to this dose now, I freaking want more.
And that’s how it spirals into more and more.
At least once a week (that you’ve already seen isn’t necessarily true) and other drugs isn’t a good sign.
And yes I detest this system because working with children in care I’ve seen them become way too addicted.
This rhythm at 40 is not normal. Once a month maybe for a huge let it all loose party with the guys ? To each their own in that situation.
Just look at all the celebrities it destroyed, and they had plenty enough money for any type of fun.
Also, I really wish you to know that some types of drugs can very quickly cause a high addiction more than others : please don’t ever try some random thing with him to try to understand what it feels like
