I've been involved as a drug & youth volunteer for nearly 6 years now and the people who say "It doesn't cause me any problems" are just about the worst cases. While this sounds terrible for a worker to say, I rarely couldn't care less if people do drugs. What bothers me is when their drug habits cause trouble for other people. If a bunch of guys want to sit in their lounge room and smoke pot or inject heroin all day, go for it, no skin off my nose. If they want to go to a nightclub, take googs, start fights and harrass people then that's not on. In a handyman/landscaping business I own/run, I have 3 employees that are addicted to illicit drugs. It doesn't affect their work or their relationships so I have no issue with them working for me and most of my clients feel the exact same way. Oh, I very rarely drink, don't smoke and I don't even go near caffeine. I get drug tested on average every 2 weeks between booze buses, work and doctors plus I have a heart condition. It wouldn't be very smart for me to touch anything.
