Ismene, yes LSD is stable in very easy to keep conditions (room temp, away from light and oxygen, etc.) as you have illustrated, and yes, of course it'll degrade in a hot car or an oven; however, please don't make your argument into an indirect attack on the Black Pirate. That goes for your posts too Black Pirate, you don't need to tell people you reported them, us mods can see that you reported it and will deal with it accordingly. Making a post about it simply adds more to the thread clutter that you two are spewing all over PD's storage threads. In fact I'd really like it if both of y'all would cut it the heck out, agree to disagree. Stop making personal attacks. Ignore each other if you have to, hell, argue via PM, but please keep it out of the threads from now on... please.
OP, it is not nearly as unstable as many used to believe. In poor conditions, it will degrade, but if you take simple precautions it'll keep fine for decades. There are other threads about this though, one was even posted just a week or two ago, so I'd say your question is answered. When it comes down to it, degradation studies are far and few between, but there is plenty of anecdotal evidence that LSD has no noticeable degradation if you take the precautions of keeping it below 80 degrees, and away from light, oxygen and particularly moisture. Desiccants near the container are a common practice.
