I understand your concern, and I agree that it is painfully annoying to have to review the actual law.
However, if I simply provide you with basic discussion of Arizona law on this issue, you would not be fully informed, and you could still make an error which would create liability for your organization. Consequently, I believe that it is absolutely necessary that you review the entire law, so that you can be fully informed.
That said, I have made a diligent search of the internet, looking for something that you could use as a guide. And, while I haven't found anything that I believe is legally sufficient, I have found the drug test policy which is used by Honeywell Corporation
. Given that Honeywell is a huge multinational organization, I believe that this policy statement is probably as good as you could get from any law firm on the subject, since Honeywell undoubtedly had numerous in-house attorneys work on this policy statement, before it was issued to employees. The policy expressly states that it is applicable to Arizona. Here is the link.
Let me know if this is helpful, or if you need more information. Thanks again!
