The Veteran's service-connected depressive disorder with anxious distress and cannabis use disorder prevented him from obtaining or maintaining substantially gainful employment, granting a TDIU effective September 11, 2020.

The Board granted service connection for left hip iliopsoas tendonitis, right knee strain, and left knee strain as secondary to lumbosacral strain. Service connection was also granted for cannabis use disorder as secondary to mental health conditions of PTSD, major depressive disorder with alcohol use disorder, and TBI. However, the Board denied an initial disability rating in excess of 70 percent for PTSD and granted a separate disability rating of 40 percent for TBI.

The Veteran withdrew the appeal for service connection for a psychiatric disability, including depression, alcohol use disorder, cocaine use disorder, and cannabis use disorder.

The Board remands the claim for service connection of an acquired psychiatric disability, to include unspecified bipolar and related disorder with anxious distress, cannabis use disorder, and other hallucinogen use disorder, due to missing records and a need for additional evidence.

The Board denied the veteran's claims for an initial compensable rating for right eye diplopia and extraocular motility restriction, service connection for traumatic brain injury, and service connection for an acquired psychiatric disorder to include PTSD. The claim for cannabis use disorder was remanded.
