And all heavy marijuana use starts with casual marijuana use, but it would be incorrect to claim all the ills of heavy marijuana use as consequences of casual marijuana use.Why? The point of reforming the prison system is because the prison system is bad. That has nothing at all to do with what laws lead to prison time.We did give it a shot. Prohibition gone, Mafia thrives. Boom. Now you can (try to) find a case where a prohibition was repealed and organized crime diminished.Not at all. We may be no closer to resolving the central point, but we have learned a lot. We've learned which people don't care about science at all (e.g. Methais, subzero), we've learned which people care about science but can't be bothered to read the science I link (e.g. yourself, Warriorbird), we've learned which people care about science but can't be bothered to read the science
they link (e.g. Fallen). Heck, we've learned what specifically the central point is! It's useful both for this discussion and discussions in general to recognize ways people can get sidetracked.By the measure of casual use carrying long term (post-intoxication) risks for the entire population, putting themselves and those around them at risk of harm.I'm willing to restate what I have repeatedly said in the past, sure.

As I've also repeatedly said in the past, no matter how small this rate of risk appears at face value, it is higher than the one we tolerate for all other legal drugs.Alcohol is not directly responsible for that many deaths. Alcohol poisoning is a risk of only 1 per 1,000,000 (and please note that this is alcohol poisoning, not alcohol and a bunch of other stuff at the same time poisoning). A guaranteed amount of the populace will abuse anything: alcohol, aspirin, paint thinner, glue, high fructose corn syrup. The only sensible path is ban those things that are dangerous
in themselves, and rely on robust, invasive regulations to restrict people to appropriate use for those things that can be used safely. You bring up that 12 year olds shouldn't drink, pregnant women shouldn't drink, drivers shouldn't drink, and my response is that I never advocated for open season on alcohol. I actually find the current system of alcohol regulations that ban all those things pretty in tune with current science... just like I find the current federal system of marijuana regulations. A guaranteed amount of the populace will break those laws and regulations, too, but the same reasoning applies. We're not going to abandon the rule of law any more than we're going to ban everything.Neither (2) nor (3) are correct. I believe prohibition has a causal force downward on drug usage, but that only implies that drug usage will go down in the absence of all other forces. I think that if you did a large enough study on prohibitions you could control for these other forces, but such sample size might not yet be available. Think of prohibition like hitting the brakes. If you hit the brakes at 70 mph (113 kilohectares per fortnight for our metric friends), you're not going to stop for quite a long time. If you've got the gas pedal floored and are gently riding the brake for some reason, you're not going to slow down at all. The only way to evaluate your brakes is to take into account these other factors, as I have done for marijuana -> schizophrenia with family history of mental illness and quantity used among many other things.
