The connoisseur is defined by choices
In recent years, the cannabis connoisseur has emerged in the culture. By connoisseur, I don't mean someone with refined tastes. I merely mean someone with choices. The consumer who stores more than one jar is a connoisseur, the consumer who buys, and consumes, a bag at a time is not.
The other two kinds of consumer are, dependent and medical, and they have some similarities. Obviously, I don't believe that someone can be addicted to cannabis. But, I do think it's possible to become dependent on cannabis, in much the same way as I'm dependent on regular exercise.
The dependent spends too much money
A dependent consumes cannabis regularly, usually every day. They always buy the strongest strain, the one with the most bang for their buck. Potency is the most important parameter of cannabis to the dependent. The worst thing about being dependent is the cost of cannabis.
Medical consumers want relief from specific symptoms
A medical user, similarly has narrow requirements, though they may not be potency in the sense of high THC. Whatever strain has the most of the hundreds of chemicals in cannabis that work for their symptoms, is the one the medical consumer is looking for. When they find that strain, they usually stick with it. Recently, CBD has been in the news and strains that are high in it are being recommended to medical users who want to avoid THC.
All that is fine, but there are literally hundreds of more chemicals to be studied. THC and CBD are just the tip of the iceberg, so to speak. Stay tuned, says Mary Jane!
Everyone is potentially a connoisseur
I really don't believe in a strict seperation of medical and recreational use of cannabis, and I doubt many who've thought it through do either. A plant as benign as cannabis is hardly dangerous to experiment with self medication. I've been telling people for years that, "It's worth a try", for whatever ails them. Compare that to the chemicals being prescribed to people with various psychiatric disorders nowdays! No sane doctor would disagree.
I predict that it will turn out that cannabis does more to improve your ability to tolerate pain, than it does to actually dull the pain. This is a gigantic 'can of worms' for the pharmaceutical companies. First, it begs the question, "is improving one's attitude about pain just as effective medically as actually dulling the pain?" If the answer is yes, then we've been barking up the wrong tree in our ways of thinking about pain for some time.
The second big, but less obvious, threat to 'big pharma' is that, if the first point is true, it opens up a whole world of mind and body together kind of thinking in medicine.
