It's diffucult to describe. It all depends on person's mental situation, concerns, character. You can't get addicted to weed, not even psychologically, it can become a habit though. Considering trips, they are influenced by the THC/CBD ratio in the strain. If you are prone to anxiety and stress don't try high THC strains because they will only make things worse.

On the other side CBD strains have true medical value for anxiety and other mental issues. Not recommended if you are going to work et cetera. It's a drug afterall.

Marijuana is one special thing, it reveals your true self. It's not just about laughing and finding simple things funny, it's a real treasure for philosophical thinking, questioning your past, present, future.

(don't use it if you or your family have a history of mental illness like schizophrenia and clinical depression because it might trigger one)

Cheers!
