Hi Ieft my drink on my desk and I am worried that a colleague has put blood or spit in to my drink and I drank it ? i left a herbal mixture I. My desk and when I can back I colleague of mine was near it whom is homosexual and was unattended. Thank you for your reply I am concerned as I don't know I if he did, it just keeos playing in my mind when I did drink it roughly 4-5 hrs later it was 2.5mls diluted in 4mls of water followed by another 5mls of water. I than remembered I left the bottle unattended and made myself throw everything up
