Well, yes, it’s “a drug”. But then, so is alcohol and caffeine. And most people don’t mind taking those from time to time.
One thing to keep in mind though, these days there’s a whole lot of strains of marijuana, and not only do all people react differently to marijuana in general, each person reacts differently to each strain as well. Some will get you higher than others. Some will help you more than others. So it’s not simply making the decision to try it, it’s also finding the strain that helps you best. That can take some trial and error.
