I am trying to find the correct way to transport narcotics for training. Some tell me that I cannot keep them in a safe in my trunk except for transport to and from training. Others say different. Also what is the cheapest way to transport them. Do I just buy a safe/lockbox from a local store and put the narcotics in tupperware or do I purchase the safes found on the ray allen website or the american aluminum website with the individual compartments to prevent contamination.
