Yes is is possible to smoke too much. I’ve done it, total pale white passed out from smoking and cardio respiratory systems most likely way in overdrive. This has happened only a couplen or few times to me out of hundreds but it’s possible.
stop smoking. Sit down. Have a friend if you can or phone call someone to keep you in check. Breathe. Drink water or better juice, eat something force it. Benzos may help or antipsychotics but do NOT DRINK it is not safe for your cardiovascular system. I have chronic hb now due to a heavy chronic meth and alcohol combo addiction. Drinking INCREASES the risk to your heart racing and spinning out of control like a crisis the way in interacts with meth.
next time smoke less or not at all as long as you can. Less meth the better it really is a terrible debilitating drug over time.
