Microscopic scans of cannabis pinpoint the individual hairs that release THC
These amazing images show marijuana in phenomenal detail, even pinpointing the cannabis sacs that store the psychoactive chemical THC on the ends of individual hairs.
Samples take several hours to prepare and have to be completely dried out beforehand so water vapour doesn't obstruct the final image, according to the professor who captured these remarkable pictures.
They are then photographed in a vacuum chamber using a computer scanner that takes around four minutes to record each image.
Pictured is an image of the top of a cola blade (the solitary leaf that extends out from a large bud). The purple heads in this image are glandular trichomes which are responsible for the smell of the plant when you brush itI like to think what a person would see if they were just a few microns tall', Professor Ted Kinsman from the Rochester Institute of Technology who is author of 'Cannabis: Marijuana Under the Microscope' told Business Insider.
'I'm trying to make science visually exciting and appealing to the general population', he said.
Professor Kinsman paints the THC-containing cannabis sacs (which are at the end of tiny hairs called trichomes) a bright colour so they stand out.
THC – short for tetrahydrocannabinol – is responsible for giving people a high when they smoke the drug.
Dr Kinsman's samples are then coated in gold and bombarded with electrons. A computer records how the electrons are scattered away from the sample.
This data is collected and an image is subsequently generated using the scanning electron microscope (SEM).
His images show how the hair-like trichomes form a matt of thorns that protect the centre of the stem from insect attack.
The images also show a cannabis seed after three days of incubation before it is transferred into the soil or a hydroponic system.

To achieve this image, female plants were grown right next to male plants each in full bloom. The pollen is 20 um in diameter. A single grain of pollen is too small to see with the human eyeold plant shows a very different view of the leaf (pictured). This part of the plant is also protected by long hair-like trichomes

Pictured are the numerous trichomes found in the fold of a young bract leaf. The older the leaf, the higher the chances the trichomes have stuck together or collected dust
