Just got this from a trusted IRL friend:

 

Summer Safety Alert

Methamphetamine cooks are buying propane tanks from the exchanges at Wal-Mart,
Kroger, and emptying them of the propane gas. (undertermined)

 

Then they fill the propane tanks with anhydrous ammonia, which they now use in a recipe
to cook Methamphetamine. (true)

After they are finished with the propane tanks, they return them to the
store. The stores refill the tanks with propane gas, unknowing to them
the improper substance that was inserted in the tanks and sell them to
their consumers. undertermined)

 

Anhydrous ammonia is very corrosive and weakens the
structure of the tank. It can be very dangerous when mixed with propane
gas and hooked up to a grill, recreation vehicle, etc. (true)

You should inspect the propane tank for any blue or greenish residue
around the valve areas. If there are evidences of these substances, do
not purchase the propane tank and advise the vendor of your findings. (true)
