It seems that the results replicate themselves when it comes to the effects of cannabis use on the adult brain. Little or no harm to the brain can be established in adult use, including heavy use. The only way to get the brain damage or harm to the brain in monkeys is to literally smother them with the equivalent of 200 joints of smoke all at once and they were harmed or died from lack of oxygen if you look up how these tests were preformed on the monkeys. A gas mask was used to get the 200 joints worth of smoke into the monkey. They died of asphyxiation!!!! Look at the medical facts for yourself and how the tests were done. As I’ve said before with just a little typing you can find out for yourself.
