Hi, Welcome to HCM.
Cannabis causes increase in heart rate
and blood pressure. Based on your cardiovascular conditions it will worsen your condition. I will strongly advise you not to take it. In regard to your anxiety
and sleep disorder
there are many better and safer medications than cannabis that will help you get relief. In this regard I will advise you to consult a psychiatrist
and certainly a cardiologist for your cardiovascular conditions.
Hope this helps.
