hi im an over weight woman and am forever trying faddy diets! a month ago a friend of mine, who had recently lost five stone, suggested i try her diet...the drug speed. im law abiding and in anyother circumstance would never have tried an illegal drug never mind not know where to purchase it! my friend suggested i try a bomb of hers, so i did, i didnt like the effects it had on me and would never do it again, but im now worried because im due to take a medical examination for a university course, i dont know what the examination entails? and im frightened the drug may show im my ulrine or blood sample? can you advice me on this matter? i am 16.5...5ft7..and 32 years of age....
