This was already brought up and no not really. Because its too easy, like dandelions its a weed, it can grow like wildfire anywhere and naturally, without human interference.
Interesting fact, we actually had some MJ grow wild in my parents yard all on its own a few years ago.
But my point is that prohibition doesn't work so why have it? Would it not be better to simply make illegal the effects of mis-use than use? Since prohibition ended alcohol has been legal to produce, sell, and drink if all of the licenses and such are in good order. As a result the alcohol tends to be a "safer" product than the corn-whiskey being made in a rusty still in the backwoods of Alabama or the stuff people were "somehow" getting a hold of my other means.
With the ending of Alcohol Prohibition we now have a safer, purer product that has to meet the standards of the ATF and I'd assume the FDA or some other agency that will ensure the product is as "pure" as possible. (I.E. it's not "watered down" to get the most out of it.) We regulate its sale through taxes and licenses and there's fines and jail-time not to mention other things in place for those who abuse it or cause destruction/death under its influence.
Now, I
do draw the line at opiate-based drugs, meth and stuff like that as those drugs have much more drastic problems associated with them, are for more dangerous, and the chance for overdose also greater. It can also be argued they're "controlled substances" as variants of them are used in prescription pharmaceuticals.
So if marijuana (a mostly harmless drug) were legalized we'd have a way to make a purer product that will benefit consumers, it'll be a safer product that'd be a benefit for consumers, we'd have just as many ways to control, tax, and regulate it as we do with alcohol and tobacco and we'd be just as able to prosecute people for using the stuff in situations where they shouldn't. (Like driving.)
People in these arguments often say, "Would you want your doctor to smoke a joint before operating on you?" and I respond with, "No, but I'm going to assume he's an adult and won't do that anymore than he'd drink a beer before operating on me."
There's just no logical reason I can see for MJ to be illegal, none. Meth, Cocaine, Heroin all of that, sure, I can see the reasons. Those are serious drugs that can cause serious problems and their effects are some of the strongest of all the drugs that are out there. Compare Charlie Sheen (a present/former heroin/cocaine user) to pretty much any comedian out there right now: Louis C.K., Zach Galafinakis, Seth Rogan, hell if they're a comedian there's a pretty good chance they're likely presently on, or once on, MJ. All of them maintain good, regular, jobs and are hardly self-destructing louers. (I will defer that it's "possible" they've done, or do, other harder drugs too.)
I swear, the movie Refer Madness is a nice example of how I think post people think of pot-heads. It's entirely stupid.
And, again, I've never used the stuff. Never plan to even if it were legalized. (Oh, okay, I might try it once.) But I fully understand the irrationality of it being illegal when alcohol is acceptable.
The War on Drugs is just more of the government trying to force the population into a narrow way of life that some see as ideal, mostly on the Right side of the aisle, and it's stupid.
If some guy wants to get high on MJ, let him. He's harming no one.
