Raphael Mechoulam, Ph.D., who is considered “the father of cannabis research,” has about 400 published articles in the medical field…cited over 100,000 times in peer work. It’s about an hour-long video, but a lot of good info.
“Beyond the role of cognition in vulnerability to substance use, the concurrent and lasting effects of adolescent cannabis use can be observed on important cognitive functions and appear to be more pronounced than those observed for alcohol”.
This was an actual] clinical study of a population-based sample of 3,826 seventh-grade students from 31 schools consisting of 5% of all students entering high school in 2012 and 2013 in the Greater Montreal region.
This as opposed to the article you cited in JAMA which was not a clinical study but alternatively was a Meta-analysis or review of a group of studies and can be found at the following URL;
The difference being the NBC article was quoting an actual clinical study. The article you quoted is a meta-analysis or comparison of a group of studies not an actual clinical study
The mistake was easily made by one biased or a novice in clinical trials and clinical studies and the jargon or terminology used in both. --BadKarmaKyle
I don't think that this cited study says what you think it says. The lasting effects dissipate after 72 hours which was cited in the JAMA study (which was referenced by NBC if you look); these so called "lasting effects" don't last any longer than the withdrawal period since THC is fat-soluble; due to the solubility, as one withdrawals from the absence of marijuana, the fat-stored THC enters the blood stream continuously until the subject is completely detoxed, so yes, the minimal effects last longer than alcohol since alcohol isn't fat soluable, but the effects aren't nearly as harmful --not even remotely close. You could also say that the effects of cannabis last longer than cocaine, opium, meth, and many other drugs that aren't fat soluble, but we all know that alcohol and these other drugs are far more harmful to the body than cannabis will ever be.
Professor David Nutt demonstrated this rather well; I would google it. By the way, cannabis ingestion leads to neurogenesis (birth of new brain cells), and it can shrink cancerous tumors despite the nonsense that disinformation agents have been putting out for years. This was demonstrated by Harvard University in a cannabis study in 2007, and it was also demonstrated (and scrapped by the DEA) at the Medical College of Virginia in 1974. Please contest me on any of these points, because I promise that I can back every one of them with solid evidence. Even Harvard Professor Dr. Lester Grinspoon would agree with me. It seems that I'm not the one that doesn't know how to read clinical research. Those "lasting" effects from cannabis ingestion don't last any longer than the withdrawal period, and the adolescents will end up being more healthy than they were before.
Dr. Tashkin showed this nicely in his UCLA study that demonstrated that cannabis smokers had better lung function than people that didn't use any drugs at all. You should read more.
