Hi there ~
I understand your concerns. The rapid pulse as well as painful spasms due to marijuana are not uncommon symptoms. I am glad that you have since stopped the usage of weed and would encourage you to consider the same with regards to smoking
cigarettes as well. I also think that the family history of anxiety
is making your condition worse and you may also have heart problems. Getting a cardiac profile and consulting a qualified doctor who can help with your illness symptomatically while you try going off of marijuana would be one way to deal with things. A consultation with a psychiatrist
may also be helpful in quitting smoking cigarettes.
I hope this helps. Take care and have a lovely day!
