<p>Answer: There’s no good reason why marijuana is banned, except maybe that it is easy to cultivate underground and thus would be hard to make a state-run monopoly out of, or to tax heavily.</p>
<p>It’s not addictive (spideygirl, onus is on you here - repeated studies have proved that marijuana is not physically addictive, and that even the psychological addictiveness potential is low), the gateway drug hypothesis has been disproved, and it has also been shown that smoking marijuana doesn’t cause COPD, emphysema, lung cancer or any of the other health issues associated with tobacco. The only negative effect is an increased incidence of mental health issues among long-term smokers. Conversely, THC has actually been shown to prevent cancer cell growth.</p>
<p>So, HisGraceFillsMe, yes, I can go around saying that pot has no long-term effect on those who smoke it. You know why I can do that? Because I’m backed up by medical fact, instead of exaggerated, factually deficient cultural mores.</p>
<p>As for abuse, here’s a chart visualization of a UK study which polled doctors, addiction psychologists, police officers and counselors about the relative addictive potentials and harmfulness potentials of a number of drugs: <a href=“http://en.wikipedia.org/wiki/Image:20drugs.gif[/url]”>http://en.wikipedia.org/wiki/Image:20drugs.gif</a>. As you can see, pot comes out as one of the least harmful drugs there.</p>
<p>The basic answer as to why pot is illegal is cultural. America is culturally against marijuana. Over time, that will change, because younger generations are gradually getting less and less taken in by the alarmist untruths surrounding pot. Additionally, while society as a whole has done a very good job at fighting a rear-guard action against the truth of the harmfulness of various drugs, it can’t forever; eventually it will becomes impossible to deny that we have legalized some of the more harmful drugs in existence, and banned some of the least (alcohol vs. ecstasy, for example). I don’t know where I want the trend to stop, but I will say that at the moment the war on drugs is costing society a great deal, screwing up a lot of people’s lives, and not giving any positive effects back in return.</p>
