OG 18 is also popularly referred to as 'Private Reserve'. Being the indica dominant hybrid strain that it is, it has a kick unlike any other. The buds are dense, thick and extremely resinous. There is no denying that the strain is incredibly sour, in fact it is so sour it will curdle milk instantaneously. As for the taste, it is as sour as it smells but should not frighten you from giving it a try. The strain and its taste are so overwhelming it will want you come back for more, although you should refrain from smoking higher doses. The strain is quite strong overall. It offers a perfect mix of body and cerebral high that will increase focus and concentration. Even though it packs a punch, it does not last as long as you would expect it to last. But then again the finish is not as nasty, it is relaxing and clean without any negative effects or crashes. Its all-purpose body feeling will leave you relaxed, which is excellent for any patient suffering from pains and aches.
