No, tu no esta un pequeno nino en Ingels aqui. Yo estoy quatro anos quando yo escribo aqiu! But I will reply in English so that others can follow.
True that plant patents are only valid and upheld in 1st world countries, but the future I see is going to be dominated by corporate industrial growing of OGiCK clones here and no longer importing weed from the 3rd world. I doubt that the home growing market will be anything like the landscaping market with plants like roses and fruit trees though. Patents will likely be enforced at the clone level in industry rather than for home growers. They cannot come here on my property and bust me for cloning patented roses, unless I try to sell them or make money off of them. The high impact aspect of Monsanto that people fear though is GMO and things like the death gene that prevents viable seed from forming, prevents cloning and prevents growing and flowering for more than one cycle. And in places like Uruguay, they are actively asking companies to develop Cannabis genetic markers to show that the clone or strain is local to Uruguay.
I doubt that the USA will ever sign an international treaty over transfer of Cannabis seeds and genetics. I am sure that there will be legal cases brought against growers of certain strains that certain people claim to own or have patents on. But that will likely be at the national level, and not the international level. Certainly the Chinese will continue to ignore all patents, copywrites and trademarks. globally that stuff is impossible to enforce. Meaning that growers out there will no longer have the big money markets here that they are losing now to legalized weed.
As for the likes of the cartels n Mexico, they are already reacting to the lower demand for weed. Or rather, from what I have heard, farmers in states like Sinaloa and the Baja states in Northern Mexico are just not growing Cannabis any more because the prices they are getting are too low. The same thing is going to happen here to small growers once things ramp up to a super-massive growing scale, as is being seen now in Canada, Colorado and Massachusetts. In the US, Canada and EU we can crank out pot on an industrial scale with ease. Just look on YouTube. Though on YouTube there is also video on a massive cartel outdoor grow that was busted by the Federales in Baja (Baja Norte or Sur, I forget which). That MJ grow site was HUGE! Disguised with camo netting and all.
Also keep in mind that legal weed in Oregon at least was intended to specifically drive out the black market for weed. It seems to be working. I can buy weed at the local dispensary for 100 an oz. after tax. Good fresh grown local bud/nugs, certified and tested for residue and strength. I do not think that the cartels can make enough money on $100/oz or $13/eighth weed. The black market has been above the $4,000 a pound range for a long time, but as of today the average outdoor grown pound of legal weed here is (Cannabis Benchmark price) is $1,200. Which leaves slim margins and can crush the black market price. At any rate, the cartels are already shifting back to more meth/ice and coke/crack, and opioids. Mexican brown heroin is on the rapid rise here to satisfy the habits of people addicted to Rx opioids like Vicodin, Codine, Tramadol, and oxy. That has created a source of anti-marijuana lobbying, in a (what I believe is false) claim that smoking weed leads directly to the use of harder drugs. The counter clam is also being made that legal weed reduces the likelyhood of using opioids, and marijuana is available as a soft landing replacement for people addicted to them. I do not like opioids myself, and have a low tolerance for them. I have been jacked up on pharma grade Dilauid and Morpheme in hospitals, and I did not like the feeling on either one. I also do not like taking Vicodin. So I am not a junkie, but I am most certainly a pot head, and have been for about 40 years now.
