Some drug abuse affects your brain as much as stress does or even worse. Not using drugs is a way better option, as stress is not an excuse to allow drugs toward yourself.

Have you ever heard the phrase "curiosity killed the cat?" it's simply saying that curiosity can be dangerous, in this case, the phrase is correct. If you think you're just going to try drugs once and nothing will happen, then you'd be very lucky. Most of the time that "once" turns into a twice, then a third time, to maybe an addiction. Even if you do try it once you might have a huge allergic reaction.
If you try drugs for attention, the only attention you are bringing to yourself is negative. You are better off bringing attention to yourself in a more positive way. (sports, art, music, social, grades)
