Morphology
get + high + on + one's + own + supply
The literal parts ('get' + 'high' + 'on one's own supply') yield a clear image of becoming intoxicated from using your own stock, so a learner who knows the words can partially reconstruct a related idea. However, the usual figurative sense — becoming overconfident or deluded by one’s own products/ideas — is a metaphorical extension tied to cultural/drug-related usage and is not fully predictable without prior exposure, so it is only partially transparent to a B1 learner.
Etymology
Get high on one's own supply comes from drug sellers: imagine a dealer who uses the drugs they sell, literally getting high on their own supply. That's why it now means 'become too pleased with yourself or ignore real problems with your own work or product'.
