Heartburn felt. Reflux or heart disease?

I smoked some marijuana last night at 8pm. Before that I had 2 bottles of beer and 2 samosa. After having the marijuana I was feeling anxious and was having a heavy heartbeat and a heart burn. After 24 hours I am not high, heart rate is normal, no breathing issues as well. But I have the heart burn. A burning sensation is felt on my heart and sometimes it is felt on the entire chest and upper stomach as well but mostly on the heart. I don't have pain or pressure or squeeze feeling in the heart it's just the burn. Is it because of acid reflux or heart disease? Point to be noted this has not happened before but only happened yesterday. Earlier I was diagnosed with acid reflux where I had burn on my throat. I have taken liquid digene twice today and one medicine of acid reflux in the evening. It didn't help much Please advise.
