Hi there ~
I understand your concerns. If you are addicted to smoking
poppers, it is most likely to explain your symptoms of being dependent on that as well as marijuana, smoked in any form. I believe that it could turn out to be a lethal combination and quitting the medications will be good for your health. I also think that there is plenty of evidence on pubmed to let you know of the ill effects and lethality of such drugs. I hope you do your reading and consult a psychiatrist
who can help you deal with these issues as soon as you can.
I hope this helps. Take good care of yourself and have a lovely day!
