Opioids storing codeine pills: Best way and how long will they hold?

[beforethebeginning]

Managed to score some pure codeïne pills which i'm not going to take anytime soon.
They're in a little bottle that has already been opened, so they're no longer in their Original protective plastic.

How long can i store them in a cool and dry place,
and whats the best way to store them?

I was thinking to maybe buy a machine thats able to vacuum seal plastic bags,
or will the pills be just fine in the little bottle?

How long are you planning on storing them? You can use rice and things like that, but realistically for anything up to 24 months, a bottle should be fine in a dry cool environment.

2 years sounds good maybe more who knows.
so a bottle which has already been opened, i can just throw some rice in it close the bottle and store in cool & dry place?

^You could go crazier than that if you wanted to, and I'm sure someone here could give you an even better technique, but for LSD tabs, I used to wrap them in saran wrap, fold that in magazine paper, and then put it in a jar surrounded by rice...That's how I was taught...It may not matter, but i'd use something to seperate it from direct contact with the rice...

I believe, the drug itself will remain stable for a long time, but some of the other components that make up the pill, cornstarch etc., don't keep as long....but this is all from experience, not actual scientific proof...but 2 years, yes...at least

Edit: Oh, the reason I mention blotter LSD, it's much more fickle than what you're talking about...more susceptible to mold, moisture etc.

but I'm pretty sure codeine will remain stable for several years, but I could be wrong...
