Have not heard of the use of hemp patches. I have seen CBD oil, Moxie drops, Dixie drops help a few people with anxiety, decreased appetite. I have also seen elders on marijuana get more agitated.
Hemp patches.... not enough track record to advise to use. For some CBD, particularly, Dixie Drops and Moxie Drops have been helpful for appetite, sleep, or anxiety. Sometimes, especially with more THC it can lead to psychosis and agitation... and too much can lead to sedation and falls.
