Since it is now legal, any company, Government or Union regulations prohibiting Marijuana use, while not at work, would be grounds for a wrongful termination lawsuit. The smart ones have already quietly rewritten there policys. Most ask employees to not use marijuana 8hrs prior to working, mirroning the alcohol policy. Only workers that maintain some Federal licence(TSA, FAA, USCG) are subject to lawful "marijuana" drug testing in Alaska. The only unclear issue is what the State will do about driving. Will it be a subjective test to establish impairment?
