Check the use by date (if it has one)
are they in a blister pack? as this would be better,
but I’d say a year or two after the use by date should be ok if in the origional sealed blister pack –
as after my uncle died there were some Lorazeppam a good few years out of date and they were fine,
if not in a blister pack – mmmm, wouldnt have a clue but not long and prob not more than a year but this is a guess and I have no real evidence to this
My mate was once told if you dont seal up you puff (pot) it evaporates – he was so stoned he just replied ‘ I wondered where it kept going?’ totally serious like! ha!
