It is thought by others and myself taking in the whole idea that Cannabis in nearly every part of the world is in danger. Man's law makes this plant a hunted plant. It is yanked out of the ground where it is found and forced to extinction in the wild by man. The evolution of the Cannabis plant could have changed over the years due to the plant knowing this. The plant could evolve to make itself more desirable by providing a high drug trait, and terpenes that create the smells and tastes that we are all so fond of. If Cannabis was allowed to flourish and live in the wild everywhere there would be no headband or sour diesel growing in large fields, there would be hemp. One plant would pollinate another, and another, and eventually the plain ol Hemp plant with Zero drug trait would be the end product after the muddy gene pool. So your Girl Scout Cookies, your Double Purple Doja, your Space Queen. and Grape Stomper plants are actually safer in this illegal society. With close to Zero pollen floating in the air we can have our evolved keepers. With time and the law keeping our favorite strains illegal I predict the Cannabis of today will just keep getting better and better and better. I see this already happening in the past 5 years. The seed market now is thriving and nothing like what it was before. All thanks to Uncle Sam. Bet he wasn't thinking this would happen. 20-25% and higher values of THC on plants that smell like fruit and candy.. Hahhaaa. Fuck them.
This is just a theory but a good one IMO.
Danger of Inbreeding-
"Should inbred Cannabis be attacked by some previously unknown pest or disease, this genetic uniformity could prove disastrous due to potentially resistant diverse genotypes having been dropped from the population. If this genetic complement of resistance cannot be reclaimed from primitive parental material, resistance cannot be introduced into the ravaged population. There may also be currently unrecognized favorable traits which could be irretrievably dropped from the Cannabis gene pool. Human intervention can create new phenotypes by selecting and recombining existing genetic variety, but only nature can create variety in the gene pool itself, through the slow process of random mutation."-Robert Connell Clarke
It is also worth mentioning that Inbreeding is a useful tool used to restore Vigor to an established line. But natural inbreeding in the wild can prove to be disastrous.
& to all those old stoner dudes out ther complaining that their weed was better and saying the drugs back then were so much better... I don't buy it. I think their tolerance used to be lower and they thought they were higher due to the fact that once one gets used to anything.. the high is never as good as it once was. I remember being a new smoker and the first itme I got really really baked. It was almost like a trip. I don't buy what those old dudes are saying and nothing else can convince me otherwise. My father who actually went to Woodstock.. agrees with me. & he loves his SpaceDawg.
