Is it possible to use expired medicines as a fertilizer?

my students conducted a study on that matter. Results show that expired multivitamins is effective in enhancing the chlorophyll content of plants as compared to commercial foliar fertilizer. More chlorophyll means more sunlight is trapped more energy is produced resulting to the growth of plants. But that is just for growth, we dont know yet the effect of expired multivitamins to the nutritional value of plants:)))
