The expiration date on my mace spray has expired...how do I check to see if it's still potent?

inside the nozzle opening there is a color coded piece of plastic, if you can look directly at it while it is actively spraying you can tell the potency. red=still good.

Throw it out. \n\nIt's true that many medications can be used beyond their expiration date, and in fact they are often shipped to third world countries where they are sorely needed.\n\nUnfortunately, insulin loses its potency more quickly than most drugs. If it isn't potent enough to control your blood glucose you could potentially end up in the hospital with diabetic ketoacidosis.\n\nPlay it safe. Get some fresh insulin. You and your health are worth the effort.

how were you measuring the pH? if it was a pH meter maybe it wasn't calibrated correctly/ recently?? or if it was with litmus paper.... maybe it went bad? I'm not sure if it can... check and see if there could have been an expiration date. i don't think temperature would have that drastic of an effect unless you did the experiment at pH7 and a seriously high (like about 60C) temp and the other ones at room temp or 37C (body temp)... sorry i cant help anymore then that, that's very strange!

Will it survive OTR in an 18-wheeler from New Jersey to the Bitter Springs, TX Medical Arts Pharmacy and six months shelf life without losing potency, decomposing or melting into a glob?\n\nIf not, how about refrigerated?\n\nWhat is the expiration date for each?\n\nSomething like that?

When I was younger, there was a bottle of Old Spice that went around our family for about 8 years.\n\nI have it now, still sealed in it's box.\n\nThey don't even make this kind anymore.

It recently finished disarming. It will probably dissolve as there is no need for it now. Nearly 100 years of war got it nowhere. I'm not sorry to see it go.

Depends on the date it expires -  not the %.  Also, if you leave one or the other out on the kitchen counter that would factor in too.

There should be an expiration date on the package.

Okay Batman, here's the deal. That weed you got from Spidey was a bit past the expiry date, paranoia is a possible side effect, as is a huge ego. Lucky for you, it seems apparent you suffer from neither.

Flush it down the toilet. Whatever it might be, it may be old, contaminated from the location where it was "found", or ineffective or simply not good for you.\n\nJust flush it and be done.

Lots (if not all) of the yahoo email users are getting this. It isn't any thing for you to worry about. akamai is an ebusiness marketing company working with yahoo. There digital certificate is showing up as expired. If you look at the details it shouldn't expire until 2007. Strange.

I'm not sure how you managed to type that question in your condition, but I applaud your concentration. ; )\n\nIf it's pepper spray, check the below link:

You'd have to be wasted to try in the first place! LOL!!!\n\nHey -- if you're raiding the spice rack, try this instead.\n\nEat about 1/4 cup ground mace.  Mace contains the same psychotropic agents as DMT and some of the agents found in MDA.  Bear in mind, your stomach may feel like you just drank gasoline.\n\nIt's supposed to work.  I never was desperate enough to try.\n\nMace and nutmeg are used by prisoners -- a fairly common bit of prison lore.\n\nSome South American Indians use mace/nutmeg powder to induce euphoria. I've seen films of their use -- they use a large bamboo tube to blow large amounts into another's face, who sucks it in through nose and mouth, then typically spends the next half hour retching and writhing, then passes into a kind of stupor or altered state. \n\n\nDisclaimer: I don't endorse or recommend this activity, and you may become very ill or in some cases die.\n\nFor more info, check out:\n\nhttp://www.erowid.org/plants/nutmeg/nutmeg_journal1.shtml

I didn't know that stuff expired.\n\nMaybe it won't be as effective, but I doubt it's dangerous.

`In that case, I didn't answer your 'question?'\n\nBTW:  Your ganja is WAAAAAAAAAAY over it expiration date.

Your question makes it sound like we come with expiration dates or "best if used by" dates. There is no set age. Eveyone is different.
