A cathinone like substance has shown it’s ugly face again, my advice to all people (including the youth of the day) is to avoid mephedrone as if it was the plague.
What I can not understand is why it has not already been banned, UK law on offensive weapons covers “Any article made or adapted for causing injury, or intended to cause injury”. I would say that bath salts such as magnesium sulphate (epsom salt) which are able to simulate a mineral rich hot spring in the comfort of your own house are made / intended for washing your body.
However bath salts containing a psychoactive drug to my mind are clearly not intended for cleaning your body. I think it is a ploy to evade the spirit of the law. I think it is the same level of “wrongness” as the idea of selling scotch whiskey in the school dinner hall as a pencilcase cleaning agent, or how about pints of strong cider as a mouth wash for teenagers sold in the sweet shop !
