Sorry Anon, but I have to disagree...
I live in Canada where it gets brutally cold, so I have put a car heater in my vehicle set 60 degrees F.
I store my benzos in my car because I live alone and have nobody to dole out the recommended doseage for me.
Otherwise I will take more than precribed.
I live in n apt building and it is a pain in the ass to get to my car...it's at the other end of the parking lot, and at -40 degrees, it is a good deterent.
One night my car heater malfunctioned, the drugs froze and thus became inert.
What a waste.
It also states on the package insert to store between 59 and 80 degrees F.
So take it for what it's worth.
I wish I didn't know now; what I didn't know then
