3. Hemp Oil

This should not come as a shock to anyone that knows diddly about hemp. It’s a plant that is closely related to marijuana but does not contain significant levels of THC, the compound which gives marijuana it’s much-sought-after effect. Hemp does contain some THC, but someone would probably have to smoke a joint the size of Blackpool Tower to get high off it, and by that time they would likely be dead from smoke inhalation. Hemp has been cultivated for centuries and has all kinds of industrial uses, but it can also send you home from the drug testing lab with a grade of “H” which is two grades worse than “F,” so lay off the hemp oil (as healthy as it may be) prior to a drug test.
