I've had PVC's for about a year now and haven't used marijuana for about 6 months, but I've been craving it lately like you wouldn't imagine. I first began smoking marijuana at age 18 and continued to use it off and on until I was 21, then I stopped. Shortly after I quit, I also quit using Xanax 2mg/day and Klonopin 2mg/day cold turkey, which was the most painful experience I've ever endured. At the time, I was on Remeron for my depression and anxiety which completely eliminated my pot cravings because, after 7 years of taking antidepressants (SSRI's) that didn't work, I finally found one that did, thus, my desire to self-medicate vanished. Unfortunately, it stopped working and, as a result suffered a nervous breakdown and began smoking again. The PVC's started after my nervous breakdown; my resting heart rate rose 30 points in a matter of months and I had terrible bouts of PVC's and tachycardia. Unable to cope, I am now taking and SSRI again (Lexapro 5mg), Xanax 2mg/day, and Atenolol 50mg/day, in addition to therapy. I am now more depressed than ever, since antidepressants don't do anything to alleviate my depression; I feel helpless, alone, and misunderstood. Marijuana works wonders for me, but it elevates my heart rate into the low 100's and makes my PVC's more noticeable, so I don't know what to do. I've tried everything, from prescription drugs to Jesus Himself, and nothing helps, nothing. I tried drinking, which worked for awhile, but it now elevates my heart rate and PVC's, which is a good thing, since I'd probably be an alcoholic if it didn't. I just want to light up a joint and feel better...what should I do? Can it lead to cardiac arrest in people with occasional PVC's in a structurally normal heart? My depression, anxiety, and PVC's are causing me to lose my hair; I can literally pull it off of my head.
