MK Ultra, also known as "MKU" and "MK Ultra OG," is a potent indica marijuana strain made by crossing OG Kush with G13. This strain produces euphoric effects that are fast-acting and best for when strong medication is desired. MK Ultra is bred by T.H. Seeds and won 1st place Indica at the High Times Cannabis Cup in 2003 and 2nd place in 2004. This strain gets its name from the methods of mental manipulation employed by the CIA’s Project MKUltra. Indoor growing is facilitated by the plant’s short stature, and its above average yield delivers particularly sticky, dense, pungent flowers.

This is the perfect “nightcap”, right when you’re getting into bed and rewinding. This is one of the few strains that doesn’t make me feel paranoid if I get too high.

Smoked this in the morning on a day off without knowing what to expect from this strain. Felt the effects right away as some others mentioned, it is definitely strong body high! I wouldn’t describe the sensation as couch locked, gives a relaxed feeling without being sleepy. I could definitely do chores or errands if I needed to but the small tasks just don’t seem as pressingly important as they usually do. I’m not getting the talkativeness that some other reviews mentioned, almost the opposite. Some strains make me feel a little antisocial so that’s not atypical for me personally. But what I like about this strain is that feeling is not at all accompanied by anxiety or paranoia. Just an overall mellow, cozy, day at home type of strain

My personal favorite. You start to calm down and that warm fuzzy feeling starts to sit in. Find a comfortable seat, turn off the lights, turn on the blacklights and pick some good tunes. You might be here awhile but that's a good thing. Definitely be careful if you have a low tolerance. It has a long lasting high that is very euphoric. Gets almost hallucinogenic if you keep smoking. Hard to find in my area so if I run across it I stock up.
