Never! I dont care what people do in the privacy of their own home. Personaly i dont see any difference in having a few beers or smoking a joint after work. But the government isnt going to give anyone something they don't have to.
These people who are at Amazon need to be careful. From what i understand if your hurt at work and have a drug test. If you test positive your federal workmen comp benefits are denied. So now your hurt cant work and without a paycheck. Marijuana is still illegal federally.
