For a little while in my teenage years, my friends and I smoked marijuana. It was fun. I have some fond memories of us all being silly together. I think those moments of uninhibited frolic deepened our friendships.

But then we all sort of moved away from it. I don’t remember any big group decision that we should give up weed. It just sort of petered out, and, before long, we were scarcely using it.

We didn’t give it up for the obvious health reasons: that it is addictive in about one in six teenagers; that smoking and driving is a good way to get yourself killed; that young people who smoke go on to suffer I.Q. loss and perform worse on other cognitive tests.

I think we gave it up, first, because we each had had a few embarrassing incidents. Stoned people do stupid things (that’s basically the point). I smoked one day during lunch and then had to give a presentation in English class. I stumbled through it, incapable of putting together simple phrases, feeling like a total loser. It is still one of those embarrassing memories that pop up unbidden at 4 in the morning.

We gave it up, second, I think, because one member of our clique became a full-on stoner. He may have been the smartest of us, but something sad happened to him as he sunk deeper into pothead life.

Third, most of us developed higher pleasures. Smoking was fun, for a bit, but it was kind of repetitive. Most of us figured out early on that smoking weed doesn’t really make you funnier or more creative (academic studies more or less confirm this). We graduated to more satisfying pleasures. The deeper sources of happiness usually involve a state of going somewhere, becoming better at something, learning more about something, overcoming difficulty and experiencing a sense of satisfaction and accomplishment.

One close friend devoted himself to track. Others fell deeply in love and got thrills from the enlargements of the heart. A few developed passions for science or literature.

Finally, I think we had a vague sense that smoking weed was not exactly something you were proud of yourself for. It’s not something people admire. We were in the stage, which I guess all of us are still in, of trying to become more integrated, coherent and responsible people. This process usually involves using the powers of reason, temperance and self-control — not qualities one associates with being high.

I think we had a sense, which all people have, or should have, that the actions you take change you inside, making you a little more or a little less coherent. Not smoking, or only smoking sporadically, gave you a better shot at becoming a little more integrated and interesting. Smoking all the time seemed likely to cumulatively fragment a person’s deep center, or at least not do much to enhance it.

So, like the vast majority of people who try drugs, we aged out. We left marijuana behind. I don’t have any problem with somebody who gets high from time to time, but I guess, on the whole, I think being stoned is not a particularly uplifting form of pleasure and should be discouraged more than encouraged.

We now have a couple states — Colorado and Washington — that have gone into the business of effectively encouraging drug use. By making weed legal, they are creating a situation in which the price will drop substantially. One RAND study suggests that prices could plummet by up to 90 percent, before taxes and such. As prices drop and legal fears go away, usage is bound to increase. This is simple economics, and it is confirmed by much research. Colorado and Washington, in other words, are producing more users.

The people who debate these policy changes usually cite the health risks users would face or the tax revenues the state might realize. Many people these days shy away from talk about the moral status of drug use because that would imply that one sort of life you might choose is better than another sort of life.

But, of course, these are the core questions: Laws profoundly mold culture, so what sort of community do we want our laws to nurture? What sort of individuals and behaviors do our governments want to encourage? I’d say that in healthy societies government wants to subtly tip the scale to favor temperate, prudent, self-governing citizenship. In those societies, government subtly encourages the highest pleasures, like enjoying the arts or being in nature, and discourages lesser pleasures, like being stoned.

In legalizing weed, citizens of Colorado are, indeed, enhancing individual freedom. But they are also nurturing a moral ecology in which it is a bit harder to be the sort of person most of us want to be.
