Do you think I have a problem since I've huffed 5 cans of air duster in the past month
That sounds like a lot. Are you planning on using these drugs again?
I'm going to buy more cans tonight to escape the pain of existence.
Doing drugs like aerosols may make you feel better temporarily, but they are no way to deal with issues in your life. Try dealing with your problems head on rather than avoiding them.
I'm going to huff because I want pleasure and to forget life's issues.
Huffing drugs is not a solution to your problems, and really can lead to a serious addiction. Is there a support group you can attend or a therapist you could call. Talking to someone can be a much bigger help than using drugs.
