Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. As per your query you have symptoms of numbness in the body after smoking Marijuana which is because smoking Marijuana produces intense excitation and leads to anxiety symptoms which can lead to dizziness, head pop, sudden inflow in head and severe headache. Need not to worry. It is not permanent and you should avoid smoking smoking weed. If ever you will take that go out for ventilation and not in closed space. You should take anti anxiety drugs like Beta Blockers especially Propranolol or Atenolol can help to reduce your symptoms and take benzodiazepams as well. Visit physician once if anxiety attacks increasing as this is something you need proper check up and you have to quit your habit. If still symptoms keeps on persisting visit neurologist once and get complete examination done and start treatment accordingly. Hope I have answered your query. Let me know if I can assist you further.
