Code of conduct for hypnotists
There is a great deal to be said about the depth and specifics that any professional Code of Ethics has to be written into it as far as what a hypnotist is allowed to do and what they are barred from or discouraged from doing when it comes to their professional practice and their client’s rights and well being. There are so many things that any practicing hypnotist/hypnotherapist has to be so very careful about doing and many more things that are either out-of-bounds for moral and/or ethical reasons; or just plain not allowed because they cross not only the client’s right to a safe treatment environment but also many different legal statutes as well.
If you are treating a client for an illness that is either previously diagnosed or un-diagnosed at the beginning of your treatment services, you need to be very careful that you do not cross the line into practicing medicine without a license (hypnotists and hypnotherapists are not licensed, only certified) unless you actually do have enough qualified general medical training to accurately diagnose a physical ailment.
You also need to make very certain that you outline every important detail with regards to treatment plans and all available options, the fees that are to be paid for your services as well as how those fees are to be paid and by whom. If you do not let your potential clients know up front and well ahead of their first appointment with you, you are in serious breach of the Code of Ethics in this respect.
There are a few other things that you cannot do when it pertains to your clients and the treatment plans that you have set up for them.

You may not set up any unreasonable schedules that the client(s) must follow, unless the specific situation dictates this, and even then you must consult with other colleagues who have more experience than you yourself do.
Another thing that you cannot do is to extend the treatment time or suggest treatment options that are either not the proper treatment options or more expensive than the treatment that best fits the client’s needs at the time of service. This is also a breach of the Code of Ethics.

The main reason that the Code of Ethics was created and adopted in the first place is so that all practicing hypnotists/hypnotherapists have a solid and well thought pout, well words set of guidelines that they must work within in order to provide the best quality services to their clients and to assure those same clients that the person/people that they are coming to for counseling and advice are not going to end up doing things that will further injure or harm their clients in any possible way, shape or form.
