BTW.... Smell is just another trait..much like the overall structure of the plant.
It's not a clear indicator that would lead one into thinking the plant will produce a high to make you think the heavens have opened, and the angle's are singing just for you.
it's just a common myth thats always...(at least as long as I can remember) been asociated with cannabis.

On the otherside of the token though...
Their are some strains that are very smelly..(the mear thought of handling them makes you nervous for the rest of the day), and carry a killer high!

Pound for pound, or oz. for oz., cannabis is one stinky plant. It diffiently ranks (..hehe) up their with top 10 most smelly plants on earth...IMO. and pretty sure most people in horticulture would agree.

At best what it could tell you...(mostly breeders) alittle something more on which parent has had an influence, and perhaps what to expect.
