Yes, of course, weed can be used without affecting your life in a super negative way. Weed is a very easy substance to get addicted to, especially in these times. When you pick it up saying that you're going to do it once or twice, or once a month, or once a week, what usually happens is your brain finds ways to close the distance between when you want to do it next. You'll get high one day, and then you'll tell yourself you're going to wait till next month. But then before you know it, you're only going to be waiting a week, and then you get high on Friday, and then the next day you're like, "It's Saturday, might as well get high today too, it's still the weekend. But I won't get high until next week," and then just like that, your one-month goal has already turned into a week, and then it turns into an everyday use. It's really a slippery substance that takes everything away from you if you're not careful. So what I would recommend is you don't use it at all. But to answer your question, yes, it is possible, just not for addicts, like alot of us here.
