Are you confirming that from experience?

Everything out so far on PUMA says that employers can't discriminate against applicants who have their card (who would obviously be testing positive for THC on a drug screen). The law states that employers could only take action against you for consuming during work hours.

Everyone else responding to this also seems to say otherwise... I'm guessing it's somewhat industry-dependent, but for most folks situations, I'm not sure if what you're saying holds up (no offense - just haven't seen/heard anything yet to back that up).
