Hi there ~
I understand your concerns. Pain and weakness in arm after smoking
marijuana are normal symptoms. If you have a history of stroke you probably have a higher risk of having one another time and need to take precautions especially with your congenital heart problems. If you need to consult a psychiatrist
you will also do well with consulting a counselor for the medications and therapy part of substance abuse
. I hope you consult a doctor as soon as possible.
I hope this helps. Take care and have a lovely day!
