Head CT shows no signs of bleed. What is the most likely etiology of her stroke

hytertention. she's on warfarin which makes blood clot less likely. her BP is extremely high. I'd go with that.

involuntary intoxication

Explanation:

Involuntary poisoning is a term used to justify a person's inability to reason due to the use of medicines, drugs or alcoholic beverages. People who have suffered involuntary intoxication cannot discern the real from the imaginary and for this reason can do illegal and dangerous things that endanger both their own safety and the safety of others.

Mary used a medicine that interfered with her perception of what is real and what is not. For this reason, she ended up arresting her neighbor against his will, committing a crime. However, Mary only did this because of the influence of the drug, so we can say that Mary suffered an involuntary intoxication.
