Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

It is better to avoid cannabinoids as it can increase your intra cranial pressure and may affect the shunt. Also cannabinoids in the body may interact with anesthesia drugs and produce unwanted complications during the surgery. So it is safe to avoid marijuana as of now.

Hope I have answered your query. Let me know if I can assist you further.

I was born with tachycardia, honestly not sure of the specifics, but I think it s supraventricular tachycardia. I m 17, and it has never caused any problems, but when it does occur, I always know to calm myself and just wait it out. Without consulting my doctor, I tried marijuana a while ago, and have done it 9 more times since. On my last time, I had the shakes, and a rapid heart rate. Luckily my mum was around, and was confident that I was fine, but I was, i guess, having a minor freak out considering my high. She still assures me that it wasn t life threatening or anything, but obviously opposed to me smoking illegal drugs. Since then I ve given up smoking, and that was about 3 months ago. Essentially, I just want to know if it is safe to smoke marijuana with tachycardia, as I never really knew the risks I may or may not have been running.

Is it safe to be smoking marijuana while taking lymecycine? I recently had a really bad reaction to smoking marijuana. I threw up and felt sick for a few days. I know this may be seen as me whiteying , but I never had such a bad reaction to smoking weed before. I am currently taking lymecycline for ACNE treatment, and I m not sure if my bad reaction was due to any interaction with the marijuana and lymecycline.
