Smoking weed is a slippery slope because it's very easy to become psychologically dependent and the more you smoke, the more you need to smoke to get the same effect. Also, the come down is not fun. You might feel good when you're high, but this only makes sober reality even worse. So you want to get high again, and the same thing happens.

Meanwhile you begin to lose a grip on reality, can feel like your life is out of control, and other areas of your life may be negatively affected (such as school work, relationships, finances, etc).

I used it as a coping mechanism for a while and I can honestly say that it's not a good idea for people who are prone to feeling unstable.

I agree that self harm is not a safe way of dealing with things, but nor is smoking weed. There is a thread on self harm alternatives here and as the above posters have said, they will gladly give you more suggestions once they know what you've already tried.

If you have any more questions, feel free to ask.
