What is the toxicity ceiling for methadone and alprazolam?
Answer:
what ever amount of the meds that cause breathing to stop or slow to a perilous level... and that amount vary from person to human being depending on tolerance level (i.e., how much your body is used to taking on a regular basis).
You can try to do a LD50 (Lethal Dose 50) experiment on lab animals. Or you can asked for the MSDS (Material Safety Data Sheet) from the suppliers or from the internet.
my friend was allergic and be sent to the hospital for 3 weeks.
dont do the methadone
Depending on what the Methadone is for ? This would be your Doctor's call on how much you can or can't give somebody a lift, as for the other I do not even know what it is. Methadone I have be on for a number of "YEARS", 10mg tablets taking 180mg's a sunshine and was even taking highly developed prior to this amount. This though was and is for "PAIN" (Back Pain to be persice), not for drug foul language!
Check with your doctor, I hope you enjoy one and are not just going to try it on your own ?
