My friend has recently obtained a G of speed uk speed so hes assuming its not going going to be methamphetamine as its rare in the uk. my friend has experience using MDMA and is intending to use the phets at a rave and wishes to know what the dosage for a newbie should be. the other thing that concerns me is hes not sure on what precautions he should take such as drinking water on mdma temp control etc. any help would be appreciated and sorry if this has been asked before i cant seem to find it for him.
