The question How to determine if pilots in crashes flew again? made me think about the Human Intervention Motivation Study programme (see the answer https://aviation.stackexchange.com/a/65410/14197) which has been featured in many news stories over the years.
an occupational substance abuse treatment program, specific to commercial pilots, that coordinates the identification, treatment, and return to work process for affected aviators.
This programme operates in the USA.
Do equivalent initiatives or programmes with similar aims exist in other regions? If not, is the fate of pilots who have found themselves on the wrong end of the law as the result of substance or alcohol abuse at work markedly different in other regions?
