I purchased x 2 saliva kits for my daughter to take with her when clubbing due to increase of date rape cases at the club's she uses. It puts my mind at rest as the event venues do not provide any tests or equivalent in the unfortunate chance that someone attending the venue becomes a victim. UK drug testing were one of the few companies that came up In a search and are affordable, efficient and quick delivery service. Would possibly suggest that the instructions for use & results could be beneficial to the user if displayed on individual kit sleeves/packets.
