I have a regular doctors appointment 2 weeks from today and haven't blazed since new years eve (and don't plan on it till after the checkup). Do any of the tests they administer to check regular health detect weed? Also I a MAY have a hernia which would mean blood tests and surgery...would blood tests for medical issues detect pot? I only smoke 2-3 times a week so I'm thinking I'll be alright but just to be safe I thought I'd check. Thanks.
