Medical cannabis has shown to be effective in various diseases that have not successfully been treated with other marketed drug products. However, the dose of cannabis is highly individual and additionally, medical cannabis is prone to misuse. To combat these challenges, the concept of data-enriched edible pharmaceuticals (DEEP) is introduced. Quick Response (QR) code patterns containing lipophilic cannabinoids, i.e., cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC), were printed using a desktop inkjet printer. This allows for simultaneously printing an individual dose and encapsulating information relevant to the end-users and other stakeholders in a single dosage unit, which is readable by a standard smartphone. Different doses of CBD and THC were incorporated in the DEEP by printing various (1-10) layers of the cannabinoid-containing ink on porous substrates, i.e., solid foams, prepared by solvent casting and subsequent freeze-drying. The printed DEEP were still readable after 8 weeks of storage in dry and cold conditions. This approach of ‘in-drug labeling’ instead of ‘drug package labeling’ provides a new possibility for developing a more efficient supply chain of pharmaceuticals and safer medication schemes by increasing the traceability of drug products at a single dosage unit level.
