Is sylvia drug?

I think what you mean is SALVIA. Salvia is a legal ethnobotanical that will provide a short but intense psychedelic trip. When smoked the effects usually begin in about 10 seconds so brace yourself...

I think what you are refering to is a substance called salvia (Salvia divinorum is the plant's name). Salvia is a drug that makes user's "trip" or lose touch with reality. After smoking the effects...

It is a plant extract from the common wild flower Salvia Divinorium.

generally speaking, if your clean for two weeks nothing will come up but it does depend entierly on the drug.

There are test which will specify the type of drug one has taken. Some simply say the category of drug taken. If you are looking for a specific drug, a test can definitely be done
