Scanning Electron Micrograph (SEM) of a sample if ice water hash or hashish. Shown in the image is a pile of glandular trichomes that have been concentrated in a unique process. Leaves with very high concentrations of stalked glandular trichomes are cooled in ice water then agitated. The agitation breaks off the trichomes, which in turn sink, to the bottom of the water. Once separated from the water and dried, the ice water hash has some of the highest concentrations of THC of any physical separation process. Since the stalked glandular trichomes are the location of the highest concentration of THC this technique in recent years has become very popular. The marijuana (Cannabis sativa) plant contains tetrahydrocannabinol (THC), the active component of cannabis when used as a drug. The spherical cells in this sample are 60 um in diameter.
