If I drive a lot drunk and harm someone I should face severe criminal charges. We have laws on the books for that kind of stuff already.
I'm a perfectly good driver at 0.15. Why are you taking my liberty away to prevent me from driving at that level?
I have never believed in the BAC standard of telling if a person is impaired. First of all there are all kinds of things that can cause a person to be impaired besides just alcohol. It would be very simple, something that a couple of guys from Anandtech could throw together in a month, to make something that tests reaction time on the roadside. See, being intoxicated or tired or whatever slows down your reaction time which is what makes you impaired and you are absolutely right. Some people are impaired after one drink even though they are under the legal limit. Some people can drive perfectly fine at .01 and driving tired has been proven to be just as bad if not worse then driving drunk. Why do sleepy drivers get a pass on DUI's when they are just as impaired as a drunk driver?
So basically I don't believe in bullshit arbitrary numbers when we could very easily test for the actual danger which is reduced reaction time.
I said that the government has the right and responsibility to protect us from harm. The government also has a responsibility to protect our freedoms.
Guess what? Sometimes you can't do both at the same time. Therefore, you must choose how far to go in either direction. Such as, choosing 0.08 as the legal limit for driving drunk.
Because I am libertarian, I believe overall that we go way too far in trying to protect us from harm and in sacrificing protecting our freedoms.
In fact, I also believe we go way too far in this regard from cannabis. Just because I draw that line short of decriminalization, doesn't mean it's not consistent with libertarian beliefs. I merely believe that the harm is sufficient to warrant some criminality as to deter its use in minors, and I believe that some criminality will help in that regard.
If you wanted to use alcohol as an analogy, let's say the legal limit was .02 (more criminal than it needs to be IMO). I am arguing for changing the limit to .08, and others are arguing to abolish the limit altogether.
You do know that kids, including myself many years ago, have far easier access to marijuana then they do beer and alcohol right? That is because marijuana is illegal and therefore sold on the black market where there basically are no rules and regulations. It was absurdly easy for me to get a bag of weed when I was in highschool. A 6 pack of beer otoh was a freaking pain in the ass. You had to find someones brother or friend that was 21 or somehow find someone willing to risk their jobs to get it for us. If I wanted weed I could have it delivered to me at friggen school before the end of the day. In just about every poll I have ever seen this trend holds true for all other kids. Since the war on drugs started the trend has been upwards of kids using drugs.
Bottom line, legalizing and regulating it will make it harder for kids to get not easier. Will there still be kids who get it and do it, of course just like some kids obtain and use alcohol. The "for the kids" line of reasoning has been proven bullshit for a long time by real hard facts even though I do think there was a slight decline or leveling off but that has been the exception as it is again on the rise. Furthermore we currently bullshit kids about drugs and they know it's bullshit. Legalizing them and teaching them the actual truth could very well lead to lower use, kind of like what has happened rather drastically with teen tobacco use which has plummeted. We didn't need to nor did we make tobacco illegal to get kids to stop using it, we just started teaching them the actual truth. Funny how that works, isn't it?
By your premise the trends should be reversed. Marijuana use should be plummeting and tobacco use should be on the rise or at least steady but we see exactly the opposite of that in the cold hard facts. So please, no more of this "think about the kids" bullshit because it's just wrong.
Edit to you personally: I am not one for political labels so I honestly, and no insult intended, don't care if you call yourself a "libertarian" or part of uncle joe bobs political party. I think all intelligent people should have at least some views that cross all political spectrums if they are honest, informed, intelligent and free thinking people. You couldn't get a quarter of the population to agree on a movie but somehow that same group holds the exact same political ideals across the entire spectrum? Basically, imho, if you hold the exact same beliefs on a vast majority of the issues as any very large group you are probably being spoon fed the answers and told what you should believe in. Personally I take in all the information I can on a subject, let it roll around in my head for a while and then come to my own conclusion regardless of what side of the political aisle it falls on. Others seem to be trying to do that to you as far as being a libertarian then you must believe in XYZ, I am not one of those people. So you have no need to defend your political affiliation with me, just your actual position on the specific issue.
