Whatever you had consumed- liquid or vapour does not matter. It possibly could have made you VERY sick- or worse. Not a waste- a timely wake up call as to how deadly addiction and the warped thinking is. For me- the decision part is almost rational. To prove I could have just one would be pure bull.
Nothing is wasted if we learn from it. So get back up, start walking again with new knowledge and experience. Do NOT try this again. Next time, speaking from experience- could be your last. IT IS THAT SERIOUS.
Support to you.
