Methadone? That for a non tolerant or novice opiate or opiod user is very dangerous. Overdoses at as low as 20mg i've heard of. I can't stop you from taking it but if i tried it being non tolerent , i'd take half a 10 do 5mg and wait and see what happens. I did methadone first a 16, banging H at 19, banging coke at 20 and now on subutex program for last 3 years. Methadone is what got me into doing harder opiates, its like heroin, just a long lasting opiate and of course H is for the rush soley. I would say don't take it your body is fuct for life once it knows a good H shot or good methadone waves, u'll crave it eventually and then like myself cant feel normal without it. Thats called DEPENDENCY, and by that point i had to score daily or i would be DOPESICK. Save urself and ur loved ones the trouble.
