get a personal air detector thing ..
PPM meter ..
itll go off if theres too much co/co2/flammable/explosive gases orrr too little oxygen ..
any good construction safety place should have one
If you can have social use of oxy or other opiates , why should heroin be any different ..
if you were shooting / smoking , i would think it was fucked up ..
but if you snorted it , I wouldnt care being in the same room at all .
silica is BAD shit bro .
best natural preservative is honey .
either (A) vac pac them and store them in a freezer
or (b) grind / mix with honey ...
the psilocybin will oxidize and turn the honey blue (this is normal) .
you can keep it like that pretty much forever .
just rent then .
also , you wont be able to get much from a "unsecured loan" without proof of income .
OR if you have a car or something of value you could secure the loan with that ;) .
good luck brother .
