Our “Better” Marijuana CanistersAll the “Better” canisters have both prescription labels and assay labels fully visible. Coloration varies widely Better Canister Better canisters have both prescription and assay labels. Many have the extra pharmacy labels cautioning against sharing the drug and advising to keep the product refrigerated. But there was never consistency with respect to these extra labels. But perhaps the award for most interesting canister markings goes to the canister featured below which was released to Robert in December 1985. Several canisters have the additional label from the U.S. Public Health Service (USPHS) but no other canister has the curious admonition “7-7-82 Do Not Ship. No Good.” Unfortunately the assay label does not include the potency of the enclosed marijuana cigarettes but our suspicion was that this canister had very low potency and was deemed at some point to be “No Good”. Robert would occasionally receive cigarettes with potency as low as 1.75% THC. In the 1990s the NIDA finally began including THC potency on the assay label.
