Would storing DMT at a balmy 98.6F for a few hour car ride be too long? I'm taking my new treasure up to the mountains for a camping trip for my first go with it, and want to hide it well for the car ride.

Freebase? My advice would be to just put in an airtight baggie, or foil to reduce/limit oxidation...of which there will be next to none in that very short time period.

just keep it dry.

Much above that (104F) and it'll begin to melt. Keep it in a container which is leak proof, and if it does melt, wait until it resolidifies, and scrap it up. May become a little yellowish in the melting and resolidifying phase change, but that, in all likelihood, is merely DMT n-oxide.

Potency loss, however, is likely to be imperceptible.

If it's going up the rectum make sure the container won't break and or be sharp. Not only might that leads to internal damage but also an intense experience. It should store fine at this temperature.

Is it really necessary to hide it up your arse? Seems a bit extreme to me if you're only going on a car journey. Are you getting searched before entering the car or something? MM odd.

tripping my arse off

im sure there is a few jokes here

Probably overkill, like you indicate. Twice in the two weeks before this trip I ended up in a lane next to K-9 units at a light after smoking a bowl of weed, and both times the cops immediately pulled someone over. I'm not sure, but it seemed like the dogs probably alerted and they profiled the youngest person in the crappiest car in the vicinity to pull over. Freaked me out a bit... just hope it amounted to nothing if people got pulled b/c of me.

Btw, I'm a girl, so arse it not necessary...

Changa/enhanced leaf looks innocuous in a tea bag among other varied tea bags.

^^ good call!
