I consider weed a psychedelic. I think anybody can experience anxiety on it.
The main issue would be how you deal with this anxiety. If the anxiety and paranoia you get on weed gets so bad that you can not handle it at all, so basically, if you cannot function at all anymore, or or if you start to seriously believe in your paranoia, then you probably should not try anything more potent.
So i think anybody who has smoked a lot of weed may have experienced some paranoia on it, like "are those people talking or laughing about me?". I think that's quite common, actually.
What's not however, is if you actually started to believe that people where talking or laughing about you. If it became absolutely real to you.
If that was the case, you may have actually experienced a psychosis on weed. Or at least you have been very close to it.
In that case....don't take DMT. or even weed.
