One who has an affinity for all things relating to cannabis. Can be a synonym for a cannabis connoisseur. A cannabist is essentially more than a marijuana smoker, he or she is a marijuana enthusiast. A cannabist can often be spotted with his nose in a baggie of bud for long periods of time, or examining a nugget or brick of hash up close with a magnifying class as if it was a piece of jewelry. Most cannabists are familiar with most aspects of cannabis culture-- breeding, growing, smoking, rolling, smoking device construction, etc. Some may contend a cannabist is nothing more than a marijuana geek.
