I have had skip beats since I was 20 now I am 55 and still have them , I find that when I smoke or eat some Marijuana it calms my nerves and stimulates my appetite , sometimes I don't eat for fear of skip beats , Like today I skipped lunch, I find that if I work out it helps , even when I get up to go to the bathroom at night when I lay back down I can feel my heart pounding until I take a few deep breaths and its gone
Canabis is not a cure, it is just hiding the symptoms by acting as a stimulant. Drugs are relaxants and they also develop the problem of paranoia over a long period of use. There are far better medications available than canabis.
