I quit smoking cannabis about 2months ago after around 3yrs constant smoking, I got anxiety from it and all the other symptoms of withdrawal. I had a ECG scan and chest x-ray and everything was fiine, recently (in the last 2 weeks) after turning down anti-depressants I have started to feel really good, much better and general anxiety symptoms have faded however I'm still getting chest pains, increasing pains only in left arm aand seeing spots, flashes whilst blliinking and lines, iim scared this is not from cannabis addicition, anyhelp please ??
