What just a few people know, is that weed is illegal all over the world due to international law. To be specific, due to the Single Convention on Narcotic Drugs treaty, an update of the Paris convention. Even though marijuana is pretended to be legal in some countries, it's not.
It is appropriate to code residuals from a new CVA when the residual is still present at the time of discharge (AHA Coding Clinic for ICD-9-CM, 1989, second quarter, page 8). A transient ischemic attack (TIA) is a temporary interruption of the blood flow to the brain.
People who have a TIA have a 25% greater risk of having a stroke or other serious complication within 90 days. In one study of people followed for 3 months after a TIA, about 10% had strokes, half of them in the 2 days after their TIA. This was more than 50 times the stroke rate expected in people of their age.
