with no fresh air....in a sealed closet.
A friend of mine was on the organ transplant list. If you ever, even once and even a little bit...in spite of your dr recommending cannabis to help relieve pain etc while you wait...you Will be Kicked OFF the list....No Organ for YOU.
Anyway, he worked with medcannabis patients...he was in a clinic...around multiple users, making topicals and other products like food etc.
The hospital UA'd him Constantly...he never Once tested positive for cannabis...however his wife smokes tobacco, he's never smoked a cig in his life.......at one point his nicotine levels went way up and they advised him that IF his elevated nicotine levels did NOT go Down Immediately-He'd be kicked off the donor list.
While this is not a controlled test ...it Is an indicator of the "REEFER MADNESS" nonsense they write.
It may be possible to rise THC levels in "Extreme" situations (saturations) for some..but in this case...and I suspect most cases..the answer is no.
What we need is Unbiased research.
