Help Hiding spots for SN?

[Caribbean Sky]

I live with other people and in the past, I've used non-opiate drugs so there is a chance of them searching old hiding spots where they've found stuff before.

Where I live is very isolated, it's lots of wilderness behind the house too. I could hide it in airtight and water type containers and wrap it up in multiple layers so that really doesn't get to it, and then hide it outside, but I don't know if anyone would recommend that.
I would much rather hide it outside than in the house if possible, but if not, I understand.

i.e. For reference there is a indoor porch, area, living room, dining room, small kitchen, bathroom, three bedrooms; two of them are lifted not by me, and an attic and basement; but the attic is not safe. Lots of nails.
You can see why I'd rather hide it outside; housemates would never ever think to look there if concerned about me.

suggestions and ideas are very welcome
(as well as details about where and where not sn can be hidden without spoilage)
thanks!

oooh. I like this.

do you have a reference image? I'm sorry, I like this idea and it sounds really good, I'm just having a little trouble visualizing what you're putting out here.
not your fault; due to illness I'm very fatigued all the time in my brain is working at half speed.
