Therapists are not infallible and like all people vary in skills and competence. Not everyone is going to benefit from therapy and for some people it will be harmful. Ditto for shrooms.

Given the expense and lack of access to therapists, for many people trying mushrooms first is probably a good option. You could have a bad time but it's very much dose dependent. Most people will just laugh a lot. Taking a massive dose and not being prepared for the things lurking in your subconscious is most definitely not recommended.

It's the usual story: if they were legal you'd have much more control over strength, variety and usage. Less people would be harmed and more people would benefit.
