> [@Homebrew](#): > > How many young men are needlessly in prison for supplying something people want? How many lives have been ruined because of some busybodies want to control other people? Good grief. _Petitio principii_. This assumes the truth of what you’re setting out to prove. Presumably, those on the other side don’t agree it’s “needless” to imprison marijuana dealers. Laws always exist to control other people. It’s up to you to show WHY this particular control should not be exterted on people. Merely inveighing against the control of people as a general principle doesn’t address the issue. ---

> [@Bricker](#): > > “The government is not my nanny.” > > Er… yes, it is. It undertakes to feed you if you can’t afford to feed yourself; to pay your medical expenses if you cannot afford to pay them; it intervenes to force your employer to pay you a minimum wage instead of letting you and your employer negotiate between you. We may well explore if keeping marijuana is an _appropriate_ exercise of the government’s nanny role; we cannot proclaim that the government is not a nanny when it serves that role in many other areas. By this reasoning, someone who successfully picks your pocket has, by that precedent, established his right to take possession of your house. ---

> [@WhyNot](#): > > **Bricker** , I agree with you. Those arguments don’t hold much water with me either. However, I believe it’s written somewhere nifty (Constitution/Bill of Rights, perhaps?) that any rights not specifically allocated the gov’ment are assumed to be those of the people. I presume you’re referring to the Tenth Amendment, which (more precisely) limits the **federal** governemnt vis-a-vis state governments and individuals. Current legal doctrines, built upon a set of definitions that make Bill Clinton look like Noah Webster, pretty much ignore this requirement through the magic of bafflegab (e.g. defining “interstate commerce” as including non-commercial intrastate acts, defining “public use” as use by private entitites, et cetera). ---

> [@Bricker](#): > > With all due respect, telling me to develop my own cites is not really the way a debate works. I’m not taking a position in the debate, but I am interested in reading the pro- and anti- sides in this debate and watching them develop arguments. If you cannot advance at least a summary of the data, with citation, that you believe supports your position, I cannot see how I will be moved to adopt your position. I’m not telling you to develop your own cites. I’m merely asking you to review the ones that myself and others have posted countless times in past debates on this very forum. To be perfectly honest, I don’t really have the inclination to rehash things I’ve said a million times here and that are easily searchable, but it does appear that many of those old debates have been lost. Also, you do seem to be genuinely curious about the issue, and I’ve always enjoyed reading your posts and have been continually impressed by the staggering amount of legal knowledge you bring to the SDMB, so I guess I can spend a bit of time digging up cites and presenting what I hope will be a sufficient summary of the available data. [Here](http://www.straightdope.com/classics/a2_225.html) is a Cecil Adams column on the long term health effects of marijuana, in which, among other things, Cecil notes that: > [@Cecil Adams](#): > > There are still a few people who think marijuana is a major health threat. But the more common view is that, while marijuana doesn’t exactly qualify as health food, on the whole it causes fewer problems than its two main competitors on the recreational drug scene, alcohol and tobacco. That column could stand to be updated with information from [this](http://www.counterpunch.org/gardner07022005.html) recent study, which found that: > [@](#): > > Marijuana smoking -“even heavy longterm use”- does not cause cancer of the lung, upper airwaves, or esophagus You may also be interested in [this page](http://www.norml.org/index.cfm?Group_ID=3475) of health-related marijuana myths. Granted, this information does come from NORML, but it is actually an even-handed and extensively-cited page on the subject. Really, there is so much information about the health effects of marijuana out there that it’s very difficult to provide anything close to a comprehensive summary. [Here](http://www.druglibrary.org/schaffer/hemp/history/mustomj1.html) is a review of the first federal anti-marijuana law, which was rooted in racism and inspired by public hysteria over supposed effects of marijuana that we now know to be laughably false. The American Medical Association unsuccessfully stood in opposition to this law. [Here](http://www.druglibrary.org/schaffer/hemp/taxact/taxact.htm) is more information on The Marihuana Tax Act of 1937. This information comes from [The Schaffer Library of Drug Policy](http://www.druglibrary.org/schaffer/index.htm), which contains more information on the subject of drug policy than you could ever possibly want to know. And here are [William F. Buckley](http://www.nationalreview.com/buckley/buckley200406291207.asp)’s thoughts on the matter of legalization/decriminalization. As far as marijuana’s effect on driving goes, see the cites from the GQ thread I linked to earlier in this thread. So basically, no, marijuana is not completely harmless, but it’s a far cry from the threat propagandists make it out to be. Enforcement of marijuana laws costs tens of billions of dollars when the government could instead be making billions from taxing the drug. In places like Holland where marijuana is decriminalized and sold openly, society has not exactly ground to a halt. Like I said, this is a pretty broad subject that is not easy to summarize, so if you have any questions, feel free to ask away. ---

In the absence of someone arguing the other side, let’s say I accept the NORML “Myths” page. It’s consistent with Cecil’s take: marijuana is not as dangerous as some make it out to be, but it has some dangers and ill-effects. That’s still not really a strong argument for legalization – presumably the “keep it illegal” folks could respond by saying even those lesser health and safety hazards are sufficient to keep it illegal. ---

Prohibition only compounds that damage and funnels money into the coffers of criminal organizations that could instead be used to create more legal jobs and generate more tax revenues.

With NIDA’s support, Tashkin and colleagues have identified the potent carcinogens in marijuana smoke, biopsied and made photomicrographs of pre-malignant cells, and studied the molecular changes occurring within them. It is Tashkin’s research that the Drug Czar’s office cites in ads linking marijuana to lung cancer. ---

**Bricker** : I am also a long-time fan of yours here on this board and I agree that whether or not marijuana is as harmful as alcohol or tobacco alone should decide if legalization is the right thing to do, but it should be a factor in deciding. The big question is “WOULD MAKING POT LEGAL CAUSE MORE PROBLEMS THAN IT SOLVES?” Not an easy question but there is a lot of issues to consider which are not too subjective… Billions spent on mj prohibition/Tax revenues to be reaped. Limited availability = less pot heads about. Possible medical benefits. Sends the wrong message to kids…. Just to name a few. I am surprised to see you sitting on the fence with this after all of your posts about the government poking about your life without just cause. The fact is the reasons pot became illegal are at the very least somewhat misleading or at most downright plain fucking bullshit! This should also be considered when one is looking for the right answer. (If I am mistaken and you **do** think the government should poke about your life without just cause, please ignore the previous line). ---

Many people go with the idea that legalising will only effect users–but generally I would bet that the base will expand a great deal. And possibly a good deal more with the price dropping. So one thing to determine when doing the math of feasibility is how much of an increase in car accidents you can expect to see start occuring when marijuana is legalised. While **neutron star** was overstating the opposing case, the evidence from countries that have decriminalized it seems to indicate that there will be no significant increase in the number of users if the US followed suit. It’s also worth noting two errors **Sage Rat** made in his post: the first, in conflation of the use of marijuana with the use of marijuana _while driving_, which are seperate issues, and more importantly, the assumption that use of marijuana impairs driving ability. There is, to my knowledge, no scientific evidence that this is the case. ---

> [@WhyNot](#): > > But **Homebrew** ’s point (and mine as well) is that this may not be true. It may be more accurate to state: “Well, unfortunately all of the \*\*people who I know are \*\*users are the jobless, break engagements because I’m suddenly interested in staring at the ceiling, types.” I know, and I admitted that. However, I am always somewhat hesitant when people take common stereotypes (which often, whether we like it or not, do have some basis in reality) and state the opposite (well, everyone I know who smokes pot is a 1600 SAT scoring rocket scientist). It’s fine to admit that the group of people you know may not be indicative of the general group of users. But it is hard to rely on the secret army of ambitious pot smokers who you can’t see, over the fairly large number of jobless pot smokers you have seen. It’s human nature, I guess. The cause and effect argument might be better; for all I know, naturally shiftless people are attracted to pot, rather than pot causing shiftlessness. ---

Hendrik Robbe and James O’Hanlon, “Marijuana and Actual Driving Performance,” NHTSA Report #DOT-HS-808-078 (1994), concluded, among other things, that driving ability under marijuana: - dangers are less than those of drunken driving - produces a moderate, dose-related decrement in road tracking ability - dangerous in emergency situations that put high demands on driving skills ---

In considering the constitutionality of a law, you cannot haul in the existence of another law and claim ITS rationality is a basis for overturning or upholding the first law. ---

Perhaps my knowledge of the law is off here, but don’t you legal types use precedents involving similar situations all the time? Isn’t that one of the core foundations of the legal system? For example, look at Lawrence vs Texas. I know you disagree with their reasoning, but it is the law of the land now and you’re the one who brought up the law and how it is argued. They compared one situation (homosexual sodomy) with other legal issues involving sexual freedom (like Griswold versus Connecticut). One of the reasons they struck down _Bowers_ was because it’s logic wasn’t consistent with the logic in other cases (Griswold vs Connecticut, Roe vs Wade). Of course, what we are talking about here is purely a matter of legislative preference instead of a Constitutional issue. I don’t dispute the right of the state to outlaw cannabis. But I still think legislators should at least aim to be intellectually honest with their decisions in the same way judges are.
