do you mean the methadone flavored syrup they give you at the clinic? You will have to do a lot of work to separate the methadone out before you can think of vaping or injecting it. not advised. please be careful.
thanks for the reply, maybe a bit more info might help, i get done from the clinic and it is a clear liquid that taste very nasty, i had a pick line so i started putting it in there, now its gone and i need a faster way to ingest. thanx again for the reply.
I would think that if you had a relatively pure sample of methadone powder and the proper equipment you might be able to get away with a very inefficient dosing method. You would definitely lose a bit of product through pyrolysis as salts tend to decompose close to or blow their vaporizing points. It is most likely not worth it in the fact that if you had a pure powder dosing would be easier and quicker based on the fact its small enough for plugging or sublingual dosing. Generally speaking it is not advisable to vaporize salts as they do decompose, some like amphetamines and others can be but the general conciseness is that if it could be done it would be done more often.
I find my liquid methadone kicks in fast enough. I was sick one morning (like stomach sick) and threw up about an hour after dosing and although there was some methadone clearly in what came up it didnt bother me.
