Elizer, I'm going to respond to you not because I disagree with what you said, but because you stated concisely the view that's opposite the one I hold, and I figure it might be neat to provide the foil view.
I don't hold my mind's current state sacrosanct. That is to say, I respect my mind incredibly, but I don't have any belief that says my mind was built the way it was for a reason, or that there's something wrong with experimenting with it. That doesn't mean I abuse it incredibly, but I'm fine with drugs and find the infrequent experiences I have with them to be worth the negligible cost they have on my mind.
I won't say "drugs are good" because I think it's stupid to assign a moral value to drugs either way. Hence, the idea that the brain should be preserved and altering chemicals avoided isn't one that I find offensive in the least. But it's worth pointing out the beneficial effects they can have on you. For one thing, realizing the limits of your perception can be fascinating. Weed doesn't have that effect on me so much, but alcohol and salvia both certainly made me realize things I wouldn't have realized otherwise. Alcohol's emotional effects certainly taught me that our moods are tenuous and that we shouldn't equate our emotional states to any sort of logical truth about the world.
Regarding weed and dulled intelligence - yes, I feel like that sometimes. I feel like that without using weed. Right now I'm in an emotive state where I feel like I'm going to grow fat and die without ever moving. Weed has nothing to do with those downer feelings. Since I first took weed, though, last February, I wrote a novel, designed a handful of web sites that I'm proud of, finished a few projects, etc., and I did it in between infrequent weed hits. It's worth pointing out that many great artists were users - Miles Davis and heroin most famously - and that using drugs doesn't instantly make you less creative. It might make you creative in a different way, but creativity is not something which can be gained and lost. It is a potential that we all have regardless of intelligence. Think of it more as a muscle than as a trait.
We're affected by chemicals no matter how we live. You live your life according to a mixture of fats, proteins, carbohydrates, and nutrients. In my mind, worrying too much about weed is like worrying about eating fats - it's certainly possible that if you take too much, there'll be adverse effects, but assuming that a single contact with a substance will change you forever is silly.
Regarding the initial question, though, hacking on weed probably won't work too well. Weed affects the sort of focus you'd need. (For certain other activities, however, like playing music, weed can help. It's not a black-and-white all-or-nothing deal.)
My advice would be to try it, since you can't really be hurt trying, but if you decide not to then all power to you.
I did a heck of a lot of research before I tried drugs at age 19, and then had a lot of fun on drugs for a few years before giving it all up entirely. My main issue with most drugs is that you can get most of the positive effects of the less addictive drugs with training, without the nasty side effects. My favorite was hashish, which I found cleaner and more clear thinking than marijuana, though it's less readily available in America. I did most of my using in Amsterdam.
The exception is probably hallucinogens, which offer some interesting experiences that are probably hard to get elsewhere, and there's some that are largely harmless. I'd advise anyone to be really, really careful about the drugs that are both chemically addictive and tolerance building. Chemically addictive means withdrawal symptoms if you're not using, tolerance building means you need progressively more not to get to the same point. Nicotine, actually, probably gives you the least bang for your buck with a pretty brutal chem addictive/tolerance building mix. Anything that does similar you need to be wary about.
As for the most commonly used things - alcohol and THC (marijuana, hash) - you really, really can get the lower inhibitions, relaxation, creativity, etc. with some mental training. Quitting alcohol was surprisingly easy for me because eventually, I was doing much worse socially on it than without it. When you're comfortable saying and doing what you think sober, alcohol just messes up your reaction times and coordination and makes you fat and sick. The hardest part about quitting was the social aspect, but after about six months when people got the message that I was really done, that fell off too. I always tell everyone drink around me, use, whatever you please, but it's surprising how many of my friends who go out with me eventually quit. It's like a hell of a lot people drink because they're expected to more than because they actually like the effects.
Anybody who wants to use social drugs should take a look at meditation and self-hypnosis, because you can get the same emotional states that you'd get with drugs through a little practice. As lionhearted mentioned, hallucinogens are the one exception.
I'd like to add the following note: for me, at least, while regular marijuana use did not particularly affect my academic abilities, it did affect my ability to meditate, both while under the influence and during the following day.
"Proper" meditation (where you forget yourself and bask in theta waves) is a definite state which one can reliably enter with regular practice. As a long-time meditator before ever trying pot, I was used to having this resource 15 minutes away, whenever I needed it.
I discovered that it was nearly impossible to achieve this state under the influence or the following day. I enjoyed using pot for it's own sake - but, I would urge you to consider your priorities in mental development. I eventually quit pot because the meditative state was so much more essential.
After training myself to remember at least one dream whenever I sleep, a few hours of REM is more than enough hallucinating each day. Some might say it is better to be hallucinating while running about the real world, but I prefer the ability to instantly wake up out of a 'bad trip'.
The other way around. Sleep deprivation and fevers can indeed induce hallucinations, but I would speculate that they are not as pleasant or controllable as hallucinations from drugs.
I self-published, since I was in high school at the time. I'd rather not say the title here, since I'd like this account to remain semi-anonymous, but if you'd like I'll gladly mail you a link to the book online.
I never got into smoking dope, but a number of my friends did. It ended up being really boring to hang around with them, they would be content doing nothing and getting stoned. I wanted to do something. They also stayed like this for a number of years, whereas I moved on, finished my degree, got a job. They are now doing working in gas stations.
