I'm high right now
Why are you high?
I'm high because of the weed I smoked earlier.
Is it legal where you live? If it isn't legal, then you shouldn't be using it because you could get into serious trouble.
It is a safe drug and I can get it legally. It helps with my anxiety.
If you can get it legally and it helps with your anxiety, then it's reasonable for you to use it responsibly. As long as you aren't driving or doing other dangerous activities after using marijuana then you're not doing anything wrong. Just be aware of the possible risks associated with its use.
