 So I smoked a little bit of weed from an unknown strain, guessing sativa and really high THC as I've never gotten a panic attack ever in my life before, and never strong anxiety from weed either. My heart was at 120bpm for at least two hours and felt painful. It is now the next day and I can feel a bit of tightness and weird sensation in my heart and my left arm is also feeling a bit weaker than my right, Is it normal for it to feel like this for the next few days? I am thinking that after a heavy stress on the heart maybe the muscles need time to relax now and are in a bit of pain.
