You just presented some strong generalizations. I’ve read over 50% of ppl over the age of 18 have tried marijuana at some point in their life. Of those, an estimated 44% still use it today. Based on your thoughts, we should see a high number of those ppl that have used cocaine or heroin. However, those numbers aren’t even close. Not even in the same ballpark. And further, that’s a large chunk of the US pop using this “incredibly dangerous” substance - wouldn’t we see a lot of people coming forward experiencing psychosis and irreversible brain damage? Does that happen, sure, but a very very low percentage. Instead, I see a ton of ppl that use it to help take the edge off and relax, similarly to ppl getting a drink after work.
Let’s see the data that support these claims. If you sub-specialized adolescent addiction, surely you are familiar with these many large studies that demonstrate marijuana is a gateway drug. I’d love to take a look... for real. I have strep throat currently, so I have some time to read up and educate myself.
You are throwing out random percentages of people that "use" it as something related to addiction?
Johnston LD Monitoring the Future study. 68.2% of US senior have tried alcohol. Are many of them truly addicted? No. Does it mean that it isn't a gateway drug? Absolutely not.
Marijuana today is far more potent than it was in the 1970's. The percent of THC has increased from on average of 1% in the 70's to 9% in 2008. It's likely 10%+ now. The resulting problems have been huge.
Endocannabinoids shape brain development see Galve-Roperh Eur Arch Psychiatry Clin Neuroscience 2009.
THC reduces hippocampal neuron activation causing permanently smaller hippocampi and poorer memory. Changing brain chemistry effects ability to regulate mood, feel pleasure, etc. See Bossong MG Adolescent brain maturation.....in Progress of Neurobiology.
You permanently damage the ability to feel pleasure, so what do you do? You move on to something more potent.
Marijuana use increases the risk of psychosis, anxiety, depression, and schizophrenia by 2-5x. On an individual basis, that doesn't seem big, but across the population, it is incredibly damaging.
Meier et al Proceedings of the National Academy of Sciences demonstrated IQ decline that is not recovered. Average decline was 7 points. That is a huge drop.
In 2006, Lynskey published a study showing roughly 16x greater risk of harder drugs after marijuana use. Keep in mind the gateway hypothesis never established a direct progression. Some studies show 1/6th of adolescents will go on to develop dependence in 2-4 years. 2006 Fergusson completed a 25 year longitudinal study showing cannabis is a gateway drug. In 2015, Secades et al Probability and Predictors of the Cannabis Gateway Effect again showed it to be a gateway drug.
As prevalence increases, we are actually seeing marijuana often being used first and transitioning to alcohol and then higher.
With that said, the majority of people who use marijuana, alcohol, nicotine, caffeine, etc. do not go on to use harder substances. That does not make them less of a gateway drug though.
