What do you guys think? Overly unethical?

Hi everyone.

Does anyone have PDF's of the SMART material? For example:

• Smart Recovery Handbook,
• Smart Friends and Family Handbook
• Facilitators Manual
• Addiction & Co-Occurring Disorders from a SMART Perspective

Is it too unethical to use it for free? It kind of feels like it should be free. Yes I know the organization needs money to run.
